Description
Structure
Specification

Cross-Roller Ring Series

Structure

With the Cross-Roller Ring, 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 Cross-Roller Ring achieves high rigidity despite the minimum possible dimensions of the inner and outer rings.

Features

Compact, Highly Rigid Swivel Bearings ,Achieving a Superb Rotation Accuracy

Applications

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

Cross roller Bearings with different Structure

Model RB (Separable Outer RingType 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.
