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 theinner and outer rings, it is optimal for applications such as joints and swiveling units of industrialrobots, swiveling tables of machining centers, rotary units of manipulators, precision rotary tables,medical equipment, measuring instruments and IC manufacturing machines.
Model RB (Separable Outer Ring Type for Inner Ring Rotation)
Cross-Roller Ring basic type, with a separableouter ring, and an inner ring integrated with themain body.
It is used in locations where the rotational accuracy of the inner ring is required.
It is used, for example, in the swivel portions ofindex tables of machine tools.
Model RE (Two-piece Inner Ring Type for Outer Ring Rotation)
Main dimensions are the same as model RB.
This model is used in locations where the rotational accuracy of the outer ring is required.
