This spindle bearing supports high-precision shaft positioning with a 25° contact angle, matched for adjusted mounting in pairs or sets. Bore diameter is 20.0 mm, outside diameter 47.0 mm, width 14.0 mm, and net mass 100.0 g. The cage is designated T, and the bearing is supplied without sealing, so external protection must be arranged separately. The restricted tolerances (P4S) and paired/set arrangement suit applications requiring accurate radial and axial location under combined loading, where consistent preload across the pair maintains stiffness and running accuracy. Since sealing is absent, lubrication must be supplied through the surrounding housing arrangement, and cleanliness of the mounting environment should be ensured to protect the raceways and cage from contamination.
