Four Point Contact Ball Slewing Bearing External Gear

Four Point Contact Ball Slewing Bearing External Gear

The four-point contact ball slewing bearing features an external gear design, making it ideal for applications requiring compact structure and high rotational accuracy. The bearing supports combined loads — axial, radial, and tilting moment — through a single row of steel balls that contact the raceways at four points. Its external gear allows direct power transmission from a driving pinion, simplifying the drive system. Commonly used in cranes, aerial platforms, solar trackers, and medical equipment, this bearing offers high rigidity, smooth rotation, and space-saving benefits.
