This spindle bearing is a single-row angular contact type with a 15° contact angle, bore diameter 65.0 mm, outside diameter 100.0 mm, width 18.0 mm, and net mass 0.461 kg. The cage is designated T, and the bearing is fitted with non-contact lip seals on both sides (2RSD), sealing the raceway while keeping friction low. It is supplied adjusted, in pairs or sets, to restricted tolerances corresponding to accuracy class P4S. The limiting speed of 30000 1/min and the low-friction, non-contact sealing arrangement make this bearing suitable for arrangements requiring precise running accuracy and high rotational speed. Restricted tolerances (C designation) support accurate axial and radial positioning when mounted as matched pairs or sets, and the closed sealing on both sides protects the internal geometry from contamination while allowing controlled lubricant retention.
