Principle
In cross roller bearings, the cylindrical rollers are arranged crosswise, with each roller perpendicular to the adjacent roller in a 90°V groove, separated by a spacer.
This design allows one bearing to accommodate loads in all directions, including radial, axial and moment loads.
Since the cross roller bearing achieves high rigidity despite the minimum possible dimensions of the inner and outer rings, it is optimal for applications such as hinges and slewing rings of industrial robots,
tilting tables of machining centers, rotary units of manipulators, precision rotary tables, medical equipment, measuring instruments and IC production machines.
Possibilities
- RU – Integrated inner and outer ring (inner and outer ring rotation)
- RB – Divisible outer ring (inner ring rotation)
- RE – Divisible inner ring (outer ring rotation)
- RA – Similar to the RB, but more compact
