Product Details

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
