BRS High Rigidity Crossed Roller Bearings INA XA/XI/XU Series

XA-XI-XU series crossed roller bearings are preloaded slewing rings, can support higher loads than four point contact ball slewing bearings, they are suited for applications with uniform rotation, low rotational resistance and high requirements for axial and radial runout accuracy and rigidity.

XA/XU/XU Series Crossed Roller Bearings Features

1. Gear teeth on the outer ring, inner ring or without gear teeth1. Support high radial loads, moderate axial loads and tilting moment loads

2. High rigidity & running accuracy

3. Easy installation, bearings can be screw mounted directly to the adjacent construction

Applications

Robots, machine tools, handling system, precision rotary table, hollow rotating platforms, radar, precision measuring instruments, etc.
