These super-precision, high-capacity, 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. They are designed to accommodate heavy loads at relatively high speeds under low to moderate operating temperatures.
