carbon mechanical seal factory
At ROC Carbon, we’re pleased to manufacture carbon/graphite mechanical seal faces from your drawings or samples, using the same high-quality materials and tolerances that are found in original equipment manufacturer parts. As experienced mechanical face seal manufacturers, our team at ROC is experienced in machining intricate details such as flow channels and ports. Our lapping capabilities encompass both carbon and hard faces up to 16 inches in diameter and to as flat as 1 helium light band. We can insert the carbon seals in metal housings (machined by us or furnished by you) by heat shrink fitting or by using specialty high-temperature adhesives.

GRAPHITAR carbon is an ideal material for use as a sliding face within a mechanical seal configuration, operating successfully against counterfaces in materials such as Silicon Carbide , Tungsten Carbide and other ceramics. GRAPHITAR is a very hard material and extremely resistant to wear. It is lubricated by most fluids so that the medium being sealed can serve as the seal lubricant. GRAPHITAR’s permeability can be controlled to allow the lubricating medium to be metered to the sealing surface or to be impervious and fully “Leak Tight” to 6 BAR pressure of nitrogen.
Seal faces can be manufactured as fully machined components, lapped to 3 light bands, as semi finished parts or as finished parts pressed to size parts.

Mechanical face seals are a complex combination of materials and design that form a system whose prime objective is maintaining the integrity of the pumping system, keeping what is inside where it belongs and preventing contamination from the outside.
These systems enable relative motion between stationary and rotating components while simultaneously accommodating some level of axial or radial movement. The technology that has been developed and implemented in these systems has become so reliable that mechanical seals are often taken for granted. The vast majority of failures of mechanical seals can be attributed to the system in which the seal is installed, not the seal itself.
One of the materials used in many mechanical seal systems is based on the fourth most common element and the basis of all life—carbon. This article will explore how this common element plays such a critical role in these complex systems.
Because mechanical sealing systems must maintain tightly controlled contact between one rotating and one stationary face, interface stability must be maintained across a potentially wide spectrum of conditions. Face flatness is critical and is measured in millionths of an inch; unexpected distortion will change the interface dynamics significantly. With the proximity of the two face materials, contact is inevitable and the materials must be able to operate with some level of self-lubricity so they do not damage each other, which would create a path across that interface that enables system leakage.
There are eight allotropes of the carbon element (see Figure 1), based on how the carbon molecules align in the lattice, that result in a range of properties from the softest version, graphite (often used in pencil “lead”) through amorphous carbon to diamond, the hardest material known to man.
Each company creates a unique recipe intended to address specific conditions that maintain the interface stability; from low temperatures (cryogenic), to water, to methane, to oil, to higher temperatures and beyond, materials exist to provide the needed capability. These materials are designed for specific conditions. One recipe cannot perform in every condition, and seal companies work with material manufacturers to provide the optimum candidate for the application.
Figure 3 shows the variation in physical properties, thermal conductivity and chemical resistance of the part according to the relative amount of carbon and graphite in the finished product.
The attributes of the allotropes, or the various forms of carbon, can be combined in specific ratios and leveraged to achieve desired responses in a system where there is relative motion between two components in terms of friction and wear, (a.k.a. tribology), along with a large temperature range and the need for corrosion resistance. Carbon is an ideal seal face material for the range of conditions within a mechanical sealing system, and is widely used.
In the same way a pencil transfers graphite to a piece of paper, mechanical carbon can transfer material to the mating face—the level of that transfer is where the technology comes into play.
Manufacturers of carbon-based materials for mechanical seal faces achieve specific tribology through formulation of different elemental forms of the carbon atom and the use of other proprietary elements. Processing these recipes results in a structure that is literally held together by atomic carbon bonds.
A mechanical seal’s mating pair is the heart of the system and the two components are designed to work together. There exist optimum pairs for specific conditions.
The components of the recipe enable the proper tribology—too much or too little film transfer would result in shortened life or performance of the mechanical seal.
Carbon is also a critical component in some of the hard face materials used in mechanical seals because it combines with metals at high temperatures to form metallic carbides. These materials include tungsten carbide and silicon carbide.
These carbides provide superior hardness and stiffness. They are not self-lubricating and therefore cannot run “dry,” but they run well against mechanical carbons.

Manufacturing of Mechanical Seals involves high precision light engineering activity. Close tolerances have to be maintained on most dimensions and lapped surface finishes to a flatness measured in millionths of an inch are absolutely necessary for effective sealing. Most of the machinery are general purpose, such as lathes, drilling machine, milling machines, grinding machines, etc. In addition, lapping machines are
Due to varied operating conditions, mechanical seals have to be carefully selected for every application. Important parameters that influence selection and performance of mechanical seals are : Fluid properties, operating temperatures, pressures, shaft sizes and speeds, space availability for installation and the type of equipment on which the mechanical seals are mounted.
Through a detailed study of these parameters, and on the basis of engineering standards developed through extensive research and experience, appropriate seals are selected and detailed component drawing are made. These drawing

There are no by-products that result from the manufacturing process. The manufacture of mechanical seals is a light precision engineering industry ; no effluent or hazardous chemicals are involved in the manufacturing
Ferrous and non-ferrous metal waste is generated during the manufacturing process. Carbon dust is created when carbon materials are turned on a lathe. Liquid waste consists of water soluble coolant oil for machine tools.
Dust collectors are utilized on the lathes used for turning the carbon inserts. The carbon dust is collected into a disposable container. Removal of carbon dust and ferrous metal waste is contracted with local refuse collection contractors. Non-ferrous metal waste is sold to the scrap metal industry. Water soluble coolant oil is disposed through normal disposal facilities available in industrial zones.
