This spindle bearing is designed for high-speed rotation at a contact angle of 25°, with a bore diameter of 20.0 mm, outside diameter of 42.0 mm, and width of 12.0 mm. Net mass is 85.0 g, and the limiting speed reaches 75000.0 1/min. The bearing features a T-type cage and 2RSD sealing with lip seals on both sides, running non-contact, and is manufactured to restricted tolerances (P4S). Supplied adjusted, in pairs or sets, this spindle bearing suits arrangements requiring precise axial and radial positioning under high rotational speeds. The non-contact lip seals on both sides limit friction while still restricting contamination ingress, and the restricted tolerance class supports tight running accuracy. The paired/set configuration allows for defined preload during mounting, matching the stiffness and speed requirements typical of this bearing series.
