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.
