Slewing Bearings

Features:The four-point contact ball bearing is separable bearing, typically available in two structuresThe four-point contact ball bearing is

separable bearing, typically available in two structures as follows: QJ 0000 – two half inner rings and one complete outer ring; QJF 0000 –

two half outer rings and one complete inner ring. The 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.
