The XSU Series crossed roller slewing bearings are engineered for large-diameter applications requiring robust combined load support. Optional integral gear teeth simplify direct-drive integration, while the crossed roller arrangement maintains precision under extreme overturning moments. Essential for slewing rings, tower crane yaw mechanisms, and wind turbine pitch/yaw bearing assemblies.
