This spindle bearing is designed with a 15° contact angle and features a bore diameter of 55.0 mm, outside diameter of 80.0 mm, and width of 13.0 mm, with a net mass of 0.182 kg. The bearing is fitted with a T cage and 2RSD sealing, incorporating non-contact lip seals on both sides. It is manufactured to restricted tolerances and supplied adjusted, in pairs or sets, allowing precise control of internal clearance when mounted. The restricted tolerance class and matched-set configuration make this bearing suitable for applications requiring high rotational accuracy and stable running behavior at a limiting speed of 36000 1/min. The non-contact lip seals reduce friction while maintaining protection against contamination, and the paired arrangement allows for defined preload settings, which is beneficial for maintaining rigidity under high-speed operating conditions.
