NRXT8013DDC8P5 NRXT series crossed roller bearings for the rotating joints

Main application: semiconductor, NSK motors, robotics

Donghua Bearings NRXT series Crossed Roller Bearings are thin-wall bearings consisting of an inner ring, a two-part outer ring, cylindrical rollers, and separators. The rollers are oriented at right angles to each other and kept apart by separators.
This kind of NRXT series Crossed Roller Bearings can sustain axial loads in both directions as well as radial loads and strong moment loads. And with their internal clearances factory-adjusted, it can be installed directly without troublesome shim adjustment. Mounting is facilitated by the outer ring parts being inseparable.
Application:
The rotating joints of robots
Indexing mechanisms
Rotary tables
