Four Point Contact Ball Bearings

Four-point contact ball bearing is a separable bearing, it can also be said to be an angular contact ball bearing that can withstand bidirectional axial load. The inner and outer ring raceways are peach-shaped cross sections, which are composed of an outer ring, two split inner rings, steel balls and a cage. It is often used in environments with insufficient installation space and high axial positioning accuracy. Four-point contact ball bearings are often used to replace deep groove ball bearings under working conditions where the axial clearance of single bearings is required to be small. Or if the installation space is small, use four-point contact ball bearings to replace the two sets of angular contact ball bearings that are paired back to back.
