Internal-tooth four-point-contact ball slewing bearing

Applications of internal‑gear four‑point contact ball slewing bearings: Lifting equipment: Used in cranes, tower cranes, stage lighting hoisting systems, and similar devices to support both rotational and lifting functions. Rotating platforms: Employed in rotating stages, exhibition equipment, camera‑support systems, and other applications to ensure smooth rotation.

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.
