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.

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.

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

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:

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.

YRT Rotary Table Bearings are the two-way thrust bearing and the bearing is fixed to the centripetal guide bearing are designed to be YRT precision rotary table bearings. In terms of load, it can withstand radial loads and can also withstand axial loads in both directions. Due to the gap less tilting moment of the YRT bearings, it is able to meet the requirements of very high running accuracy in the CNC machine tools manufacturing industries.

In the CNC machine tool manufacturing industry, YRT rotary table bearing is its main core component. It is a rotating mechanism with outer ring rotation and inner ring support. The whole series is mainly divided into YRT type, YRTS type and YRTM type. These series are also the mainstream three models for Rotary Table Bearings.

The YRT type consists of a centripetal race, a centripetal collar, a thrust washer, two needle retainers and a cylindrical roller. It is characterized by its high axial and radial load. The YRT bearing requirements for the working environment are also between 30 ° C and 120 ° C. The temperature generated during operation depends to a large extent on the conditions of the surrounding environment, so YRT also has its own limit speed.

YRT bearings are also fitted with seals, lubricated with grease and lubricated by the outer ring and L-ring. Because YRT is used in many fields, it also directly promotes the development of the mechanical equipment industry, which accelerates the development of high-speed, precision and intelligent machine tools.
