Cross Roller Rings
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 single 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, 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.
