Four-point contact ball bearings are separable bearings that can withstand bidirectional axial loads. It belongs to radial single row angular contact ball bearing. Compared to double row bearings, the axial space occupied is significantly reduced. The contact angle of SKF four-point contact ball bearings designed by QJ is 35° or 45°. The inner ring is a flat inner ring. This allows more balls to be installed in the bearing, which can give the bearing a higher load-carrying capacity. The rotation speed of the four-point contact ball bearing is very high and the operation is very stable, and its double half-ring can be removed from the whole set of bearings and installed separately, so the four-point contact ball bearing is mainly used in the engine.

Application:

◆ Car steering gear.

◆ Engine.
