Angular Contact Ball Bearings
●Single row angular contact ball bearings are mainly used for undertaking combined radial and axial loads, and also for pure radial load.
●These bearings have a high rotating speed.
●Materials of the bearings' rings are refined bearing steel GCr15 and other types of bearing steel, while balls are adopting GCr15 or ceramic.
