Product Details

Cross-Roller Ring Series

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
