Model RB (Separable Outer Ring Type for Inner Ring Rotation)

Being the basic model of the Cross-Roller Ring, its outer ring is separable while the inner ring is integrated with the main body. This model is used in locations where the rotation accuracy of the inner ring is required. Major applications include the index table swiveling unit of machine tools.


Structure and Features

With the Cross-Roller Ring, cylindrical rollers are arranged 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 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.

Concept of the Cross Roller Ring

The Cross-Roller Ring is a high-rigidity, compact, and easy-to-use product designed based on the
double cone roller bearing and angular contact ball bearing which had been popular.
