This spindle bearing is a single-row angular contact type with a 25° contact angle, designed for adjusted mounting in pairs or sets. Bore diameter is 25.0 mm, outside diameter 52.0 mm, width 15.0 mm, and net mass 132.0 g. The cage is designated T, and the bearing is supplied without sealing, matching the B72..-E design with restricted tolerances (P4S). The restricted tolerance class and paired arrangement suit applications requiring precise axial and radial location with controlled preload, typical of high-precision rotating shaft assemblies. Without integrated sealing, external protection or a suitable lubrication arrangement must be provided by the housing design. The 25° contact angle allows combined radial and axial load support, while the P4S accuracy class ensures tight running tolerances when mounted as matched sets.
