Internal Geared Four Point Contact Ball Slewing Bearings

The four-point contact internal gear slewing bearing represents a large-scale, specialized slewing bearing engineered with a sophisticated structural design to simultaneously accommodate high axial loads, radial loads, and overturning moments. This multifunctional component integrates critical roles including support, rotational facilitation, torque transmission, and mechanical fixation.

Single-row four-point contact ball slewing bearings typically comprise two main rings, distinguished by their compact architecture and lightweight construction. Within these bearings, steel balls maintain precise four-point contact with the curved raceways, a configuration that enables simultaneous bearing of axial loads, radial loads, and overturning moments—optimizing performance in demanding rotational applications.
