QJ1020 Four-Point Angular Contact Ball Bearing 100*150*24mm SUNBEARING

When only the pure axial load acts, the steel ball and the ferrule become two-point contact, which can bear bidirectional axial load. Four-point contact ball bearings can also bear moment loads, and have the functions of single row angular contact ball bearings and double row angular contact ball bearings. Four-point contact ball bearings can only ensure normal operation when they form two-point contact.
