XSA-XSI-XSU 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.

XSA/XSI/XSU Series Crossed Roller Bearings Features

1. Gear teeth on the outer ring, inner ring or without gear teeth.

2. Support axial & radial loads, as well as supported & suspended loads.

3. High rigidity & running accuracy.

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