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 RA (Separable Outer Ring Type for Inner Ring Rotation)
A compact type similar to model RB with thethinnest possible inner and outer rings.
It enables lightweight and compact designs forthe swiveling hand portions of manipulators androbots.
