This spindle bearing carries a 15° contact angle and is designed for precision paired or set mounting, with matched faces allowing correct preload when combined with an identical bearing. Bore diameter is 110.0 mm, outside diameter 170.0 mm, width 28.0 mm, and net mass 2.52 kg. The cage is designated T, sealing type is 2RSD with non-contact lip seals fitted on both sides, and the limiting speed reaches 18000.0 1/min. The non-contact sealing arrangement keeps friction low while still restricting contamination ingress, supporting the high limiting speed. Manufactured to restricted (P4S) tolerances, this bearing suits applications requiring tight running accuracy and controlled axial positioning under the 15° contact angle geometry. It should be mounted as a matched pair or set as supplied, without mixing with bearings from other sets, to preserve the intended preload and accuracy class.
