This spindle bearing carries a 15° contact angle and is set up for precision arrangement in pairs or sets, adjusted (C) for matched preload. Bore diameter is 25.0 mm, outside diameter 42.0 mm, and width 9.0 mm, with a net mass of 49.0 g. The cage is executed in version T, and the limiting speed reaches 75000 1/min, reflecting the high-speed design of the series. Sealing is provided on both sides by non-contact lip seals (2RSD), keeping friction low while protecting the raceways. The P4S accuracy class combined with restricted (UL) tolerances allows tight control of running accuracy and matched fitting when mounted as a set, which is required to achieve correct preload distribution across the pair. The non-contact seal arrangement avoids added torque, making the bearing suitable where low friction and high rotational speed must be maintained together with reliable protection against contamination. Grease or oil lubrication compatible with high-speed operation should be selected according to the intended preload and speed conditions.
