1. Structure features 

 With the Cross Roller Bearing, cylindrical rollers arc arranged crosswise, with each roller perpendicular to the adjacent roller, in a 90°V groove, separated from each other by a spacer retainer. This design allows just one bearing to receive loads in all directions including, radial, axial and moment loads. Since the Cross-Roller Ring achieves high rigidity and the precision can reach up to P5,P4.P2, despite the minimum possible dimensions of the inner and outer rings, it is optimal for applications such as joints and swiveling units of industrial robots, swiveling tables of machining centers, precision rotary tables, medical equipment, measuring instruments and IC manufacturing machines.

2.Rotation accuracy

The spacer retainer fitting among cross-arrayed rollers prevents rollers from skewing and the rotation torque from increasing due to friction between rollers. Unlike conventional types using steel sheet retainers, the Cross Roller Bearing docs not cause displacement or locking of rollers and provides a stable rotation torque. Since the inner and outer rings arc designed to be separable, the bearing clearance can be adjusted. In addition, highly accurate rotary motion is ensured through adjusting the bearing clearance to provide a preload.

3.Usage characteristics

Since the mounting holes arc provided, this model docs not require a presser flange or housing. In addition, because it has an integrated inner/outer ring structure and is equipped with washers, its performance is minimally affected by the mounting procedure, ensuring stable rotation accuracy and torque. This model Special bearings high precision bearing RU42 66 85 124 148 178 228 297 445can be used for both inner-ring rotation and outer-ring rotation.
