Axial-radial bearings are double-direction axial bearings for screw mounting with a radial guidance bearing. These ready-to-fit, pregreased units are very rigid, have high load-carrying capacity and operate with particularly high accuracy. They can support radial forces, axial forces from both directions and tilting moments free from clearance. ZKLDF axial angular contact ball bearings are low-friction, ready-to-fit, greased bearing units with high accuracy for very high speeds, high axial and radial loads and high demands on tilting rigidity. Axial-radial bearings with angular measuring system YRTM and YRTSM correspond in mechanical terms to series YRT and YRTS but are additionally fitted with an angular measuring system.

Machine tools require screw drives that can position a work piece or machine component quickly, efficiently, and precisely. To meet these requirements, screw drives can be supported at both ends by SKF super-precision angular contact thrust ball bearings. The bearings provide a high degree of axial stiffness and high axial load carrying capacity. They also can accommodate high speeds and rapid acceleration and offer very high running accuracy.

Angular contact thrust ball bearings for screw drives are well suited for screw drive applications, but are also beneficial in other applications where reliable radial and axial support is required, together with extremely precise axial guidance of the shaft.

Lower costs by using the rotary table bearing FMB. The compact designed FMB table bearing has been developed for high precision rotary motion. It reduces the cost compared to other rotary bearings since fewer components with less tolerance are used necessary for installation offering easy installation of the bearings and reducing the overall costs.

The turntable bearing can handle axial, radial, and a combination of loads. The main advantages of this bearing are the low height, easy mounting, and high precision run-out.

The super-precision balls move on highly accurate finished ways. The balls have 4 points of contact per ball offering very low, uniform, and smooth friction. As the bearings are preloaded by delivery they move with very high precision and repeatability. Values starting at 10 microns down to 1 micron can be achieved and wobble from 6 µrad down to 2 µrad.

The PTFE Teflon ball cages keep the precision balls separated, holds the bearing together, and offer smooth running performance. In case of light contaminants, the balls are self-cleaning due to the 4-point contact of balls the contaminant is pushed outside through the contact line of the balls on the raceway.

FMB turntable bearings include attachment holes to a standard configuration to attach the bearing fast and easy. The countersunk treaded holes can be used from attachment from the top and attachment from the bottom side.

A great advance compared to other turntable designs is the compact design with just 8 mm in height. It replaces bearings from other manufacturers while using double contact bearings. This results in space savings and makes the FMB the bearing of choice for major OEM customers.

Based on the groove geometry, specially designed raceways offer a greater contact surface for the bearing balls. This allows high rigidity, load ratings, and precise running. The smallest turntable bearing with an outside diameter of 140 mm offers a dynamic load rating of 6.070N and increased to 20kN for the largest bearing. The turntable bearings are preloaded before delivery by geometric matching and do not need readjustment.

The precision turntable bearing is available in sizes starting from an outside diameter of 120 to 350 mm. The inner bores start at 40 mm with a thickness of 8.5 mm and go up to 250 mm with a thickness of 12.5 mm.

Due that the turntable combines the advantages of low height, compact size, easy installation with a high running precision they are used in modern applications. Just to name a few:

Due to their high limiting speeds and very low, uniform frictional torque across the whole speed range, these bearings are particularly suitable for combination with torque motors.

YRT rotary table bearing have high axial load and radial load ,and high tilting rigidity and high precision. YRT can be used to the machine tool and other high precision machinery of the rotary table

ZYS can offer YRT series, YRTS series, ZKLDF series, YRTM series, YRTSM series rotary table bearings. About the performance comparison of YRT, YRTS and ZKLDF series bearings with the same size, the limit speed of ZKLDF, YRTS, YRT series bearings decrease in turn while the overturning rigidity of YRTS, YRT and ZKLDF series bearings decrease sequentially. YRTM or YRTSM rotary table bearings add a set of angular displacement monitoring system on the basis of YRT or YRTS series bearings, to overcome the defect of open-loop control of diagonal displacement control, and realize closed-loop control of rotary table or indexing plate, greatly improving the positioning accuracy of angular displacement.Product structure

Thrust / radial cylindrical roller bearings YRT and YRTS series are composed of two thrust roller bearings and one radial cylindrical roller bearing. Due to the special design of the internal structure of YRTS series bearing, higher limit speed can be achieved.

Thrust angular contact ball bearings ZKLDF series consist of an integral outer ring, two inner rings and two sets of steel balls and cage assemblies. Its contact angle is 60, and it is especially for the conditions with high requirements on high speed, high axial and radial loads and overturning moment.

ZYS turntable bearings are ready-to-install high-precision turntable bearings, suitable for occasions with high precision requirements and combined load. They can withstand radial loads, bidirectional axial loads and overturning moments with negative clearance. ZYS turntable bearings have the characteristics of high precision, high rigidity and high load capacity. In order to facilitate transportation and installation, screw holes are opened on the inner ring and the outer ring, and the entire set of bearings is fastened with positioning screws. The bearings are preloaded at the factory, and there is no need to adjust the clearance for installation.

Available with inside diameters from 580 up to 1030mm, the YRTC and ZKXDF series rotary table bearings from Schaefflerare suitable for multi-axis simultaneous machining applications. They offer reduced friction, increased rigidity and operating speeds, as well as more compact designs.

Based on a combination of the company’s YRT and RTC series of rotary table bearings, the YRTC range provides the basis for highly dynamic rotary axes for rapid positioning and for form milling using multi-axis simultaneous machining. Operation at continuous speeds, for example, in intermittent turning, is also possible within the operating limits. Compared to traditional combination thrust and radial cylindrical roller bearings, power dissipation is also significantly reduced. As a result of this marked reduction in friction, a significantly increased proportion of the drive torque supplied by the machine tool drive is freed up for axis acceleration – which increases machine productivity. The amount of heat introduced to the machine tool also reduces with less friction, resulting in a reduction in temperature-induced changes in the geometry of the machine, which therefore increases machining accuracy. For cooled machining axes, this means the cooling capacity can be decreased in line with the bearing’s reduced power dissipation, which in turn reduces machine tool operating costs. Due to these larger-size bearings, the savings can quickly reach values in the low kilowatt range. By using YRTC bearings with reduced friction, the control properties of the rotary axis improve, resulting in more precise geometry transitions when machining shapes and contours.

The company has also developed a completely new design of rotary table bearing based on the its innovative Ball Roller design concept. This innovation is based on a double row angular contact, thrust ball roller bearing in an ‘O’ arrangement that uses new assembly methods and a unique rolling element. For the Ball Rollers, all parts of a conventional ball that are not under load are removed. This means that around 15% of the ball diameter is cut away from both sides. The result is a ball that is flattened on both sides and which is approximately 30% narrower (and therefore lighter) than a conventional fully spherical alternative. Ball roller elements offer all the axial load handling capabilities of fully spherical balls, but allow overall bearing width and mass to be decreased by 15 to 20%, as well as reducing friction. This not only saves valuable design space, but means that the ‘slim’ shape of the ball roller, in combination with new assembly methods, enables the number of rolling elements to be increased. This in turn enables the filling capacity of the bearing to be increased by up to 90%. Using more rolling elements in the same design space results in higher load ratings and longer service life, providing opportunities to downsize products and assemblies. Known as the ZKXDF series, the new bearings enable the design of more compact, higher performance rotary table supports in the high speed range. The benefits to machine tool manufacturers include increased rigidity and accuracy, simplified assembly processes and options for reducing system or machine build costs. Due to the single piece bearing rings, the running accuracy of the rolling bearings can be more easily transferred to the machine sub-assembly. The number of joints is also reduced, resulting in increased rigidity. Also, the new bearings do not require any holes to be incorporated in the raceways for inserting the rolling elements. This has a beneficial effect on the rating life and operational reliability of the bearings, particularly at high speeds. As a transport-securing mechanism for holding the split bearing rings together is no longer required, the rolling bearings are easier to install in the machine tool and assembly errors avoided. By using Ball Roller bearings, the ZKXDF bearings provide a larger grease reservoir, which increases operating life and allows longer relubrication intervals. Also, depending on the rigidity requirements of the application, the bearing rings do not have to be centered and supported by adjacent structures across the entire height of the bearing. Often centering on part of an adjacent component is sufficient or this process can be eliminated completely. The outer and inner rings are offset from each other to enable the bearings to be screw mounted onto flat surfaces.

For high speed precision rotary tables, the company’s product range also includes the YRTS and ZKLDF series. Typically, these are used in high performance machine tools for combined milling and turning in a single workpiece clamping operation. These bearings offer inside diameters up to 460mm.
