This spindle bearing is built for precision rotation at high speed, with a bore of 17.0 mm, outside diameter of 35.0 mm, and width of 10.0 mm. It has a contact angle of 15° and restricted tolerances (P4S), giving it the accuracy needed for stable operation at speeds up to 95000 1/min. The cage is marked T, the bearing is supplied without sealing, and its net mass is 42.0 g. Being adjusted and matched in pairs or sets, this bearing is intended for arrangements where preload must be set precisely to control axial and radial stiffness. The restricted P4S tolerance class supports tight running accuracy and low vibration under high rotational speed, while the absence of sealing allows for external lubrication and cooling suited to high-speed spindle applications. The 15° contact angle provides a balance between axial and radial load carrying capability typical of this bearing arrangement.
