What is the functions and features of four point contact

Jun 04, 2021· four point contact bearing is a separable bearing, which can also be said to be a set of angular contact ball bearings that can bear bidirectional axial load. The inner and outer ring raceways are peach-shaped cross-sections. When there is no load or pure radial load, the steel ball and the ring appear as four-point contact, which is the origin of this name.
