Four-Point Contact Ball Bearings

Four-point contact ball bearing is a kind of separated bearing, also can be said to be able to bear two-way axial load angular contact ball bearing. Its inner and outer ring raceway is peach type section, when there is no load or pure radial load, the steel ball and steel ring are in four-point contact.
