This spindle bearing carries load at a contact angle of 25° and is built for precise, high-speed shaft positioning. Bore diameter is 70.0 mm, outside diameter 110.0 mm, width 20.0 mm, and net mass 0.59 kg. It is supplied adjusted, in pairs or sets, with a T cage and restricted tolerances to class P4S, and has no sealing arrangement. The P4S tolerance class and matched-set supply allow accurate axial and radial positioning when the pair is mounted back-to-back or face-to-face, keeping internal clearance controlled under the intended preload. As the bearing is unsealed, the mounting must provide external protection and a dedicated lubrication system, typically oil, to maintain the running accuracy required at the rated contact angle.
