This spindle bearing has a bore of 40.0 mm, an outside diameter of 68.0 mm, and a width of 15.0 mm, with a net mass of 0.209 kg. It is built with a contact angle of 15° and features a T-type cage. Sealing is provided by non-contact lip seals on both sides, designated 2RSD. The bearing is manufactured to restricted tolerances corresponding to P4S accuracy class, and it is supplied adjusted, in pairs or sets, allowing correct internal setup without additional matching at assembly. The limiting speed reaches 45000 1/min. The 15° contact angle combined with the P4S tolerance class makes this bearing suitable for arrangements requiring high running accuracy and stable axial guidance at high rotational speeds. The non-contact lip seals on both sides limit friction and heat generation while still restricting contamination ingress, which supports operation at the stated limiting speed. Being supplied in matched sets (C arrangement) ensures correct preload and mounting relationship between paired bearings without field adjustment.
