The 6x26 grease-coated wire rope offers a high level of resistance to abrasion, and features a compact construction with solid support for the wires—which also provides a high resistance to crushing and makes the 6x26 a popular wire rope for a wide range of applications.

Its number and relative size of the inner wires adds to both the stability of the strand and the resulting fatigue resistance. This rope’s core is its own wire rope construction—known as IWRC (Independent Wire Rope Core)—meaning it moves independent to the outer strands.

There are two types of wire rope lubricants: penetrating and coating. Coating lubricants (which include greases) penetrate slightly, sealing the outside of the cable from moisture and reducing wear and fretting corrosion from contact with external bodies.

The 6x26 wire rope class is made up of six strands of 26 wires per strand for additional wire rope strength and durability. The 6x26 features IPS (Improved Plowed Steel), EIPS (Extra Improved Plowed Steel), or EEIPS (Extra Extra Improved Plowed Steel) grade wire rope. Also available in USA-made.

KEY REQUIREMENTS OF WIRE ROPE LUBRICANTS Whilst it may be clear that good lubrication is a key part of maximising rope life, delivering the correct balance of properties in a single product is a significant challenge. A good wire rope lubricant must: Be easy, pleasant and safe to apply Achieve maximum penetration to ensure lubrication and protection of the rope core Resist wash-off and ing-off Have excellent corrosion protection Reduce friction and wear Allow easy inspection of the rope ROCOL® WIRE ROPE LUBRICANTS ROCOL have manufactured wire rope lubricants for many years. This has allowed...

PSEUDOPLASTIC WIRE ROPE DRESSING One of the most difficult problems encountered in formulating wire rope lubricants is finding the optimum balance between good penetration properties and resistance to water wash-off. Good penetration is achieved by low viscosity products such as oils but these have poor resistance Good wash-off resistance is achieved by highly adhesive grease-like products but these have poor penetration properties Until now there has been a trade off between these competing requirements. However, thanks to its pseudoplastic rheology, WIRESHIELD achieves maximum penetration...

THE DIFFERENCE IS CLEAR The key safety check for wire rope users is a visual inspection of the condition of the rope. Traditional wire rope lubricants contain black solid lubricants such as graphite and molybdenum disulphide. These materials make the lubricant unpleasant to handle and impossible to see through. WIRESHIELD™ uses an advanced load carrying system based on sub-micron white solids. The result is a nished product that is both clean to handle and translucent in use - without compromising the load carrying or anti-wear properties. Below is an illustration of the translucency of the...

Railroads rely on axel boxes, bearings and other components to function, requiring a lubricating grease of proper consistency.If the grease thins from heat generated by forces (such as those caused by wheel/rail irregularities, roll resonance and rigid body motions), it may compromise grease functionality.This test uses the ASTM D1831 roll stability apparatus to determine changes in penetration numbers caused by combined heating with mechanical stresses.Smaller changes in penetration values indicate a better roll stability.

The original ½ scale worked penetration is determined for the test grease.The grease is then placed in the roll stability apparatus and rolled for 96 hours at 82°C.The resulting grease is again subject to a worked penetration.Reported are the initial, final and change in penetration.

To safely slow down or stop a moving vehicle, brake cylinder components should move freely, rapidly and smoothly, regardless of the ambient temperature. In cold climates, this may require a brake cylinder grease that will flow properly at -40°F. This test determines the apparent viscosity of lubricating grease at -40°F.

Molybdenum disulfide (MoS2) in grease formulations helps to improve lubricity, particularly in high temperature-extreme pressure operations such as in constant velocity joints (CVJs) and ball joints.The proper level of MoS2 is important in greases. Insufficient MoS2,may limit lubricity of the grease.Excessive MoS2,may increase galvanic corrosion and wear, particularly in wet or oxidizing environments.This test determines the level of molybdenum disulfide in greases.

The grease solids are isolated through a Soxhlet extraction.The solids are then processed through a series of chemical and physical processes and a final gravimetric determination is made to determine the percent of molybdenum disulfide in the sample.

The density of the thread compound is determined. A nickel filter cone is filled with the sample, placed in a beaker and the assembly is heated to the test temperature for the test time. The mass of oil that separates from the grease is determined. The percent volume loss of oil from the thread compound is reported.

Thread compounds seal joints where pipes meet, such as in pipelines, casings, tubing and drill stems. Because many of these applications are on or under the ground for many years, the thread compound needs to give proper coverage on application and adhere to the threads for the lifetime of the piping. Additionally, outdoor assembly of these pipe structures occurs in all kinds of weather, including environments both on land and at sea. This test determines the application and adherence properties of thread compounds when applied at low temperatures often seen in northern latitudes and at high temperatures seen in tropical areas.

Thread compounds often contain thickeners including graphite and metals (lead, zinc, copper). If these components are reactive with one another or with other grease components, the grease may not be stable enough for long term underground use. This test measures gases produced when the thread compounds are heated for a specified time. The amount of gas produced is an indication of the long term stability of the thread compound.

The sample grease is placed in a perforated metal cone. Water is then dripped over the cone at the rate and temperature specified in the method . At the conclusion of the test time, the grease is dried and the mass loss is determined and reported as a percent water leaching.

Steel panels are sand blasted, dipped in test oil, allowed to drain and placed in a salt fog chamber for the specified test time. Panels are evaluated daily for the development of rust. The number and size of rust spots is reported. If the rusted area is large, the percent of the panel rusted is reported. This test can be run for a specified period of time or until failure.

Petroleum waxes are usually solids at room temperature, insoluble in water, thermoplastic and relatively inexpensive. This makes them attractive for use in a wide array of applications including glide coatings for snowboards and other sliding equipment, release agents for molds, anti-corrosion additives for lubricants, anti-settling agents for fuel oils and paints, water-resistance additives for chain lubricants, and numerous other applications. Choosing the proper grade and type of petroleum wax for a given application requires many considerations one of which is the melting point. This test determines the melting point of petroleum waxes.

The use, sale and refining of petroleum products is often dependent upon the amount of water present. This test determines the water content of bituminous materials and petroleum products including fuel oils and lubricating greases and oils for levels of water up to 25%.

Different petroleum waxes soften at different temperatures. When formulating wax-containing lubricants such as mold-release agents, rope lubricants and lubricants for skis or skateboards, petroleum wax components may be selected based on softening points. This test measures the temperature at which a sample softens enough to drop from a thermometer bulb (the drop melting point) of petrolatums and waxes.

Ash producing substances in lubricating greases may originate from either additives (typically molybdenum or zinc compounds) or contaminants (from packaging, environment or other sources). This method determines the percent of ash producing substances in lubricating grease.

The sample is placed in a clean, dried, crucible, heated, ignited to remove all organic components, cooled and weighed. The percent ash is reported. If sulfated ash is of interest (as in greases containing metallic additives) the sample is ignited in a crucible as above, treated with sulfuric acid, heated to allow the sulfating reaction to occur, dried and weighed. The percent sulfated ash is reported.

Grease is a lubricating oil with a thickener. One common thickener is metallic soap (including sodium, calcium and lithium soaps), which tend to be relatively inexpensive, and may be formulated to give water resistance, thermal stability, shear stability or other attributes. This test determines the percent soap in a grease.

The grease undergoes a series of physical and chemical separation steps which vary depending on the type of grease. The percent soap is calculated and reported.

This test will analyze conventional greases consisting of petroleum oils and soaps for unsaponifiable matter, water, free alkalinity, free fatty acid, fat, glycerin, and insolubles.

A supplementary test will analyze greases which are insoluble in conventional solvents, contain non-petroleum fluids, and/or non-soap type thickeners.

The ability of a lubricant to resist electrical flow and current potential can be determined with this test. The dielectric strength is the ratio of the thickness of the insulating material in mils versus the potential of the breakdown voltage. The breakdown voltage is the electrical potential required to overcome the material"s insulating ability. These electrical properties can determine if a material is appropriate for use in a particular electrical application.

The ability of a lubricant to act as an electrical insulator can be measured using this test procedure. Since no insulator is perfect, the amount of electrical leakage (Dissipation Factor) will determine the degree of efficiency of insulating ability. The Dielectric Constant is a measure of the insulator"s ability to resist electrical flow under increasing frequency. Together these properties help predict how the material will perform under various conditions of electrical exposure.

This method is intended to measure the coke-forming propensity of oils under extreme temperatures causing cracking and pyrolysis. The sample is placed in a crucible and heated to evaporate and reduce the material to a coke-residue or "carbon residue". Ash-forming additives can give an erroneous indication of coke-forming tendencies by adding to the weight of residue formed. Carbon residue is a useful guide in the manufacture of base oils and finished lubricants. Results differ from those obtained by ASTM D524.

The consistency or firmness of a grease can help determine its suitability for a given application. If the consistency is too low, the grease may leak out of areas it is supposed to lubricate. If it is too high, it may not flow into areas that need lubrication. Grease that has received minimal disturbance, such as being moved from sample container to test container, is considered "unworked”. When grease is stroked (subjected to shearing action) it is considered "worked”. Stroking usually changes the consistency of grease, and grease stroked for prolonged periods of time may show further consistency changes.

This test is intended to determine the consistency of a grease by measuring the depth to which a standard cone will sink when allowed to fall according to the method. The depth is measured in tenths of a millimeter and reported as a unitless number. Worked stabilities use a standard grease worker to apply a shear stress to the sample prior to measuring the penetration. This method requires 1.1 pound (0.5 kilogram) of sample. If you have a smaller quantity, please consider ASTM D1403 . For a more severe prolonged worked stability (100,000 stroke) penetration test, consider FTM 313.

Some tests, such as atomic absorption (AA) require only the non-organic (ash producing) components of an oil or grease. This test removes all carbonaceous organic material by heating the sample, igniting and burning the vapors, and placing the remaining residue in a muffle furnace. The ash can then be further processed as needed for testing.

This test measures the coke-forming propensity of oils under extreme temperatures causing cracking and pyrolysis. The sample is placed in a glass bulb and heated in a furnace at 550°C for 20 minutes to evaporate and reduce the material to a coke residue or "carbon residue". Ash forming additives can give erroneous indication of coke-forming tendencies by adding to the weight of residue formed. Carbon residue is a useful guide in the manufacture of oils and finished lubricants. Results differ from those obtained by ASTM D189.

A sample of grease is heated in the drop point cup until the sample melts or separates and runs out a small hole in the bottom of the cup. This test may indicate the temperature at which a change in state may be anticipated under similar operating conditions.

A cylindrical steel rod is immersed in a mixture of the oil and water and brought to the test temperature. The mixture is stirred for the test time and the rod is visually examined for rust. A pass/fail rating is reported. When requesting this test, please specify distilled water (Procedure A) or synthetic sea water (Procedure B). For oils heavier than water, please request Procedure C and specify distilled water or synthetic sea water.

Wax based lubricants can be shaped into sticks making them desirable for lubricating small parts such as bolts, brushes and chains. These lubricants are also attractive for use on porous materials that absorb oil, such as wood. To make the wax easier to spread, and to instill friction-reducing and corrosion-reducing properties, oil may be added to the wax. This test determines the amount of oil present in a wax-based lubricant.

Many lubricating oils contain metallic additives including zinc anti-wear compounds and magnesium detergents. The proper level of these additives is important for the lubricant to work properly. This method determines the concentration of metals (non-lead) in fully formulated lubricating oils and additive concentrates. It may be used as a quality control tool in new oils or as an indicator of additive depletion in used oils.

In producing a product that customers can depend upon, every batch must meet the same high standards. Customers want to be able to depend on batch-to-batch consistency. This test is intended as a quality control tool to insure that the level of antioxidants in a grease is adequate from one batch to the next.

A specified mass of grease is placed in the pressure vessel. The vessel is pressurized with oxygen and heated to the test temperature. The pressure drop caused by oxygen uptake during the test is measured and reported in psi or kPa. This test normally runs for 100 hours and/or 500 hours. Other times and temperatures are available upon request.

The surface tension of an oil provides a relative indication of its capillary action, its ability to spread, and its ability to penetrate small spaces. The tendency to form small droplets and to puddle on smooth surfaces can also be indicated. In mineral oils, such as electrical insulating oils, small amounts of polar contaminants may change the properties and effectiveness of the oil. Interfacial tension can be used to indicate the level of these contaminants - In general, higher values indicate lower levels of contaminants. This test determines the interfacial tension of oils or liquids and may be used on new oils as a quality control tool and for service oils as an indication of the degree of deterioration.

This method determines loss in mass of a grease or oil by passing heated air over the weighed sample for a fixed time (typically 22 hours). Because the air is heated by passing through a fixed length of tubing immersed in the same oil bath as the test cell, the actual temperature which the sample is subject to is less than the test temperature. The differential is significant (8, 10, 12°F or more) depending on test temperature. The highest test temperature is limited by the use of an oil bath (typically 300°F).

Volatile organic liquids may be found in petroleum distillates, spray lubricants, metal-working fluids, hydraulic oils and numerous other lubricating products.Release of the Volatile Organic Compounds (VOCs) during use may alter lubricant properties and emit potentially toxic vapors into the atmosphere.This method uses distillation to determine the boiling point profile of volatile organic liquids.

Stationary grease requires pressure to start flowing. Once movement begins, a different amount of pressure, usually (but not always) less, is required to keep it flowing. Viscosity is defined as the resistance to flow of a substance. Since a moving grease usually shows less resistance to flow than a stationary one, its viscosity appears to change as the shear rate changes, thus grease is a non-Newtonian fluid. The viscosity of grease observed when the grease is flowing, the apparent viscosity is determined in this method.

In this test, grease is packed into a large cylinder, which is fitted at one end with a nozzle and the other with a hydraulic piston. Pressure is applied to the hydraulic piston, which causes the grease to exit through the nozzle. When the grease is flowing steadily, the pressure is recorded, and the apparent viscosity and shear rate are calculated. Eight different nozzle diameters are tested. The report includes a graph of apparent viscosity in poise versus shear rate in seconds-1, and the data used to generate the graph. When requesting this test, please specify the test temperature.

Metals in engine cooling systems are prone to acid-catalyzed corrosion. If coolants become acidic, such as from exhaust gas leakage or coolant oxidation, system components may be at risk of damage. Buffers are often added to maintain pH at the proper level. The test determines the reserve alkalinity of a coolant; how much acid a coolant can absorb before it reaches a pH of 5.5. It may be used for new or used coolants, anti-rust compounds, coolant additives and aqueous dilutions of coolants.

The sample is placed in a beaker and distilled water is added if needed to create the proper concentration. The solution is titrated with a standardized hydrochloric acid solution to a pH of 5.5. The reserve alkalinity is reported in ml of 0.100N HCl per 10ml sample.

The sample is temperature controlled in a hydrometer cylinder.The proper hydrometer (a sealed long tube with a weight at the bottom used to measure buoyancy) is inserted and given time to equilibrate.The value is read off the hydrometer and the value of interest is calculated and reported.

Density is the mass per unit volume (for example; g/ml) of a substance. Specific gravity (relative density) is a related value of the density of the oil relative to the density of water at a specified temperature. In lubricating oils density may help predict pumpability, propensity to cavitation, the rate contaminants will settle out of the oil (important for filtration systems), and the location of water contamination. This method determines the density and/or specific gravity of lubricating oils.

Copper is malleable, ductile, resistant to corrosion, and an excellent conductor of heat and electricity. It is therefore used in numerous electrical and mechanical applications. If copper is exposed to lubricating grease and the grease reacts with the copper, the integrity of the system may be compromised. This test evaluates changes in copper test coupons exposed to lubricating grease under accelerated storage conditions.

Copper strips are cleaned, polished and half inserted into the test grease. The grease is then placed in a pressure vessel, pressurized with oxygen and heated to the test temperature. At the end of the test time the copper is examined for discoloration, etching and corrosion. If the grease-exposed copper appears to show no detrimental effects or is the same or better than the copper not immersed in the grease, a “pass” is reported.

Automobile wheel bearings are exposed to high speeds, high loads and high temperatures. To extend bearing life, and to avoid unexpected bearing failure, the grease protecting these wheel bearings needs to resist slumping, separating and softening. This test quantitatively determines bearing leakage and qualitatively reports observations of the grease appearance at the end of the test.

A specified quantity of test grease is applied to tapered roller bearings, and the bearings are put into a wheel hub spindle assembly. The torque, temperature and revolutions per minute are adjusted and the bearing is spun for the time specified in the test. Reported are the weight of grease lost and any visual observations of varnish, gum or lacquer-like material that has formed.

A standard ABEC 6204 test bearing is packed with 4 grams of the grease to be tested. The bearing is rotated at 600 rpm in the water spray chamber at 100°F (38°C) or 175°F (79°C) for one hour. 300 mls of water per minute are sprayed at the bearing assembly. The percent weight loss of the grease carried away with the water is reported. This test is a relative measure of a grease"s ability to resist removal by water.

A standard ABEC 6204 test bearing is packed with 4 grams of the grease to be tested. The bearing is rotated at 600 rpm in the water spray chamber at 100°F (38°C) or 175°F (79°C)for one hour. 300 mls of water per minute are sprayed at the bearing assembly. The percent weight loss of the grease carried away with the water is reported. This test is a relative measure of a grease"s ability to resist removal by water.

Degreasers and spray lubricants often contain volatile solvents that evaporate after product delivery to leave the treated surface coated with the intended product. If the solvent contains nonvolatile matter such as additives, contaminants or degradation products, solvent residue may remain after evaporation potentially changing product attributes. This method determines the amount of nonvolatile residue in volatile solvents.

Coolants used in engines may come in contact with many types of metals. For instance, radiators in newer engines contain aluminum, and older engines contain brass and copper; thermostats contain copper; engines contain steel; water pump housings contain cast iron and cast aluminum. A coolant that reacts with any of these metals may not be appropriate for use in engines. This test screens coolants for reactivity with copper, solder, brass, steel, cast aluminum and cast iron. It is intended for new, unused coolants.

This test is intended to give the same information as ASTM D217 Cone Penetration of Lubricating Grease, using a smaller sample size. Although less precise than ASTM D217, this method is intended for use when only a small amount of sample is available. Depending on the quantity of sample available, the cone may be either one-half scale (50 grams of sample) or one-quarter scale (10 grams of sample). This test measures the depth, in tenths of a millimeter, to which a one-half scale or a one-quarter scale standard cone will sink when allowed to fall according to the method. The predicted full scale penetration value is calculated and reported.

Some particles in grease, such as graphite and molybdenum disulfide are intentionally added to assist in the lubrication process. Other particles, called deleterious particles, may also be present in new or used greases. Deleterious particles may arise from contaminated raw materials, poor storage leading to dimerization and agglomeration of additives, and processing errors in filtration, mixing, milling and temperature control. Deleterious particles in used greases typically come from the environment or arise from wear debris. These particles may be classified as "abrasive" or "non-abrasive". Abrasive particles may damage system components and cause premature bearing failure. This test determines the amount of abrasive deleterious particles in lubricating greases. It may be used as a quality control tool for new greases, to determine particle levels in service greases and to determine the level of abrasive particles in molybdenum disulfide and graphite raw materials.

The grease is placed between two specially prepared plastic sheets. A standard load is applied and the sheets are rotated against one another in a prescribed arc. The apparatus is disassembled, and the sheets are examined for the arc-shaped scratches resulting from deleterious particles. The total number of scratches on both sheets of plastic is reported.

When an elastomer is compressed it will deform. This deformation may be temporary so that elastomer returns to its initial size and shape when the pressure is released, or it may be permanent. A permanent deformation, known as a "compression set", occurs when the compression force is so great that the elastomer will not return to its initial shape and size. O-rings used as seals in pumps, and other mechanical systems are compressed during normal use to prevent leaks in interfacing surfaces. If compression set occurs, the O-rings may no longer properly stop leaks. This test determines the compression set of elastomers exposed to hydraulic fluids.

Elastomer properties of interest are determined; the elastomer is placed in the lubricant for the test time at the test temperature.The properties are again determined and the percent swell, + or -, and change in hardness are reported.

The torque resulting from grease lubricated ball bearings rotated at one rpm is measured. The test is designed for temperatures 0°F (-20°C) and below. Torques greater than 35,000 g-cm (3.5 N-m) are considered to be technically frozen. Most military grease specifications consider 10,000 g-cm (1 N-m) to be the maximum usable limit for adequate lubrication at low temperatures. Test temperatures to -73°C can be accommodated.

Preconditioning involves heating the grease sample under vacuum for 72 hours to remove volatiles, light ends and entrained atmosphere. Preconditioning of the grease is as per Boeing specification BMS 3-25C for Vaccuum Stable Lubricants Type II and Type III. The grease is exposed to a 10-6torr, heated to 290ºF and held for 72 hours.

Consumers often associate lubricant color with quality, uniformity and as a visual identifier. End users may rely on color to ensure that the correct lubricant is used in the proper application. Producers may use color to determine the degree of refinement and/or the presence of contaminants. This test determines the color of lubricating oils, heating oils and diesel fuel oils on the ASTM color scale, which goes from 0 to 8 with 0 being clear to pale yellow and 8 being deep red to dark. It may be used as a bench mark quality control tool, a processing aid or for research applications.

Organic compounds and hydrocarbon mixtures may have acidity resulting from contamination, aging, and improper storage or conditions during manufacture. This acid may lead to problems when using these chemicals as solvents or reactants. This test determines low levels of acidity (less than 0.05%) in organic compounds and hydrocarbon mixtures including alcohols, ketones, ethers, esters and light distillate petroleum fractions.

ASTM D1662 Active Sulfur in Cutting Oils – Cutting oils reduce friction and absorb excess heat during metal-working processes.Sulfur in these formulations may be “active” or “inactive”.Active sulfur (often sulfurized fat) provides extreme pressure properties for fluids used in heavy machining operations (such as broaching) or processes involving stainless steel and hard alloys.Inactive sulfur provides milder extreme pressure properties for processes involving brass and aluminum and where active sulfur may cause staining.The choice of formulating with active vs. inactive sulfur should also consider downstream operations and pollution control.This test determines the percent of active sulfur in lubricating oils.

During storage, oil may separate from lubricating grease, possibly changing grease properties. This test measures the oil separation under static (storage) conditions. It may be used to predict separation of oil from grease in containers stored at “room” temperature. It is not intended for use with greases softer than NLGI #1.

The grease is weighed and placed upon a fine sieve screen in a Pressure Bleeding Test Cell. The test cell is brought to the test temperature (77°F (25°C)) and pressurized with air (0.25 psi, 1.7KPa) for 24 hours. Oil that separates is collected in a cup below the sieve and weighed. The percent of oil separated from the grease is calculated and reported.

Related tests: Petro-Lubricant Testing Labs offer several tests relating to oil separation. Static bleed refers to the separation of oil from grease during storage. Dynamic bleed is separation that results from movement of the grease, typically during use. Some bleed is necessary for the grease to function properly, but excessive bleed will compromise the effectiveness and life of the grease. Dynamic bleed may be increased by elevated temperatures, contamination, vibration, centrifugal forces and usage conditions.

For separation under static conditions: For accelerated tests to predict room temperature separation, consider PLTL-163 (semi-fluids), DIN 51817 (lubricating grease) and APR RP 5A3-E (thread compounds), PLTL-182 (Bulk greases), IP 121 (lubricating grease). For elevated temperature storage separation consider ASTM D6184 (lubricating grease), FTM 321.3 (lubricating grease), AAR M-914 paragraph 2.4 (brake cylinder grease), GM 9030P, PLTL-135, IEC-811 (filling compounds)

Steel bearings exposed to moisture are prone to rust. To prevent this, bearings are lubricated with grease containing corrosion-inhibiting additives. This test determines relative ability of a grease to prevent rust in bearings, including aircraft wheel bearings.

When light passes from air into a transparent liquid, the light bends, often giving the liquid a characteristic appearance. This test determines the refractive index (amount that the light bends entering the sample) of viscous liquids. It is appropriate for samples with no suspended particles at the test temperature, and may be used for both quality control and research applications. One example of its usefulness is in ethylene glycol/water hydraulic fluids, where the proper water level is essential for the fluids to provide optimal protection. Refractive index is a quick and dependable method to determine the quantity of water present in the fluid. The sample is placed in the prism box of a refractometer and brought to the test temperature. The angle at which light passes through the sample is determined, compared to a known standard and reported as a unitless number. Please specify the desired temperature.

This method provides a means for measuring the relative performance of an oil to prevent rusting of steel under conditions of high humidity. Various specifications typically call for multiples of either sandblasted or polished (240 grit aluminum oxide) test panels. After surface preparation and cleaning the panels are dipped in the oil sample, then drained for 2 hours before placing them in the test chamber maintained at 120°F for the specified exposure time. A pass is reported if the test surface contins no more than three dots of rust, no one of which is larger than 1mm in diameter. A fail is reported if the test surface contains one or more dots of rust larger tahn 1mm in diameter or if it contains four or more dots of any size.
