(Separable Outer Ring, Type for Inner Ring Rotation)

CRB series(Separable Inner Ring,Type for Outer Ring Rotation)

Its structure is that the inner ring is separable while the outer ring is integrated with the main body.without cage ,but full complement.this model is used in locations where the rotation accuracy of the outer ring is required.

CRBC series(Separable Inner Ring,Type for Outer Ring Rotation)

Its structure is that the inner ring is separable while the outer ring is integrated with the main body.with cage and full complement.this model is used in locations where the rotation accuracy of the outer ring is required.

Structure features of CRB800100/CRBC800100 crossed roller bearing: 

With the Cross Roller bearing, cylindrical rollers are 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 Crossed Roller bearing achieves high rigidity and the precision can reach up to 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, rotary units of manipulators, precision rotary tables, medical equipment, measuring instruments and IC manufacturing machines.

Rotation accuracy:

The spacer retainer fitting among CRB/CRBC series crossed roller bearing 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 Ring does not cause displacement or locking of rollers and provides a stable rotation torque. Since the outer rings are 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.

Usage characteristics

The outer rings, which are separable, are secured to CRB800100/CRBC800100  Cross Roller bearing body after the rollers and spacer retainers are installed. This procedure prevents the rings from separating from each other.  Thus, it is easy to handle the rings when installing this type.
