What Makes External Gear Slewing Bearings Special?

You benefit from the unique external gear design that enables perfect meshing with drive pinions. This configuration delivers efficient power transmission while maintaining precise rotary motion control. The external positioning of the gear teeth provides easier maintenance access compared to internal gear alternatives.

Our slewing bearings feature robust construction with two main rings separated by high-quality rolling elements. You can choose from single-row roller, double-row roller, triple-row roller, and cross-row roller configurations. Each design offers specific advantages for different load requirements and operating conditions.
