SX Cross roller bearings

With the Cross-Roller Ring, cylindrical rollers are arranged crosswise, with each roller perpendicular to the adjacent roller, in a 90V 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, 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.
Bearing features:
1.     High precision: precision at P4, P2.
2.     High rigidity: this series bearings are with preload.
3.     High load capacity: this series bearings can support axial load, radial load, and tilting load.
4.     Small volume: this series bearings can save space for the machine.
Application scope:
Crossed cylindrical roller bearings are widely applied in the precision rotary table, rotary joint of manipulator, medical equipment, and measuring instrument etc.
