This spindle bearing is a single-row angular contact type with a contact angle of 25°, designed for adjusted mounting in pairs or sets. Bore diameter is 80.0 mm, outside diameter 110.0 mm, width 16.0 mm, and net mass 0.381 kg. The cage is designated T, sealing is 2RSD with lip seals on both sides, non-contact, and the limiting speed reaches 24000 1/min. Tolerances are restricted to suit precision applications. The non-contact lip seals on both sides keep contamination out while avoiding friction losses that would limit speed capability. Suitability for adjusted pair or set mounting allows control of preload and stiffness along the shaft axis. The restricted tolerance class supports precise radial and axial guidance under high-speed rotation, matching the P4S accuracy grade implied by the designation.
