The four-point contact ball bearing is a separable bearing, of which the QJO000 type has a double half inner ring, the QJF0000 type has a double half outer ring, and the contact angle is 35°. When there is no load or pure radial load, the steel ball and the ring are in four-point contact. Under pure axial load, the steel ball and the ring are in two-point contact and can withstand bidirectional axial load. This type of bearing can also withstand moment loads and has the functions of both single-row and double-row angular contact ball bearings. It can only work properly when two points of contact are formed.
