This spindle bearing is a single-row angular contact design with a contact angle of 25°, bore diameter 30.0 mm, outside diameter 55.0 mm, and width 13.0 mm. Net mass is 0.13 kg, and the limiting speed reaches 53000 1/min. The bearing features a T cage and 2RSD lip seals on both sides, running non-contact, which keeps friction low at high rotational speeds while still limiting contamination ingress. Manufactured to restricted (P4S) tolerances, this bearing is supplied adjusted, in pairs or sets, allowing precise control of internal clearance during mounting. The tight tolerance class and matched-set delivery make it suitable for arrangements requiring accurate axial and radial guidance at high speed, where consistent preload and low runout are required across the paired bearings.
