- Commodity name: Internal-tooth cross-roller turntable bearing
The operating principle of an internal‑gear cross‑roller slewing bearing is based on its crossed roller arrangement, which enables the bearing to simultaneously accommodate loads from multiple directions. When a load is applied, the crossed rollers roll along the raceways between the inner and outer rings, thereby supporting the load. This design allows the bearing to handle high radial and axial loads while maintaining low friction, thus enhancing its efficiency.
