Four Point Contact Ball Slewing Bearings

Four-point contact ball slewing bearings  contact angle is usually 35°. If there is only a radial load, each steel ball contacts the raceway at four points. If there is only a unidirectional axial load, each steel ball contacts the raceway at two points. It can bear axial loads in two directions as well as a certain eccentric load, i.e. torque. Such kind of bearing has features and properties of both single-row and double-row angular contact ball bearings. If it is used in a high-speed scenario, two-point contact must be ensured for its normal working. Four-point contact ball bearings are radial single row angular contact ball bearings with raceways that are designed to support axial loads in both directions. For a given axial load, a limited radial load can also be supported (→ Load ratio). The bearings are separable, i.e. the outer ring with ball and cage assembly can be mounted separately from the two inner ring halves.
