These super-precision, high-speed, single row angular contact ball bearings, with 15° contact angle, with seals, accommodate radial and axial loads acting simultaneously, where the axial load acts in one direction only. Compared to the equivalent SKF E design high-speed bearings, these are suited for lighter loads.
