A Four Point Contact Ball Slewing Bearing is a type of rotational rolling-element bearing that allows one row of balls to contact the raceway at four points. This unique geometry enables the bearing to carry axial loads in both directions, radial loads, and tilting moments—simultaneously. Because of […]

A slewing bearing is a large-diameter rotational bearing that can support axial, radial, and moment loads simultaneously. It enables rotation between two structural elements, often without needing a central shaft. Slewing bearings are integral components in construction machinery, wind turbines, industrial robots, medical imaging equipment, and solar tracking systems. Traditionally, […]
