Superprecision (ABEC-7) bearings are generally used on woodworking spindles, aircraft accessory units and machine tool applications where duplex bearings are a definite requirement. By virtue of the single row radial deep groove construction and superprecision tolerances, they are capable of carring thrust loads in either direction and have relatively high-speed ability.
