This spindle bearing carries a 15° contact angle and is supplied adjusted, for mounting in pairs or sets. Bore diameter is 10.0 mm, outside diameter 26.0 mm, width 8.0 mm, with a net mass of 17.0 g. The cage is coded T, and the design is open, without sealing. Tolerances are restricted, corresponding to precision class P4S. The 15° contact angle allows the pair to take up combined radial and axial loads while maintaining stiffness at higher speeds. Since the bearing is delivered adjusted and matched as a set, internal clearance and preload are fixed at assembly, so units from a set should not be mixed with bearings from another set. The open design without sealing requires external protection of the bearing seat and clean lubrication conditions, consistent with the precision level required by class P4S.
