Description
super-precision bearings is significantly better (5 to 10 times) than standard bearings. They conform to high ISO tolerance classes such as P4/ABEC 7, P3/ABEC 9, and P2 (which is beyond ABEC 9).Primarily for angular contact types, typical contact angles are 15° (C), 25° (A5/AC), and 30° (A), which influence the balance between radial and axial load capacity and speed.
