This spindle bearing carries a 25° contact angle and is supplied adjusted, in pairs or sets, allowing precise axial and radial positioning under high-speed rotation. Bore diameter is 55.0 mm, outside diameter 90.0 mm, width 18.0 mm, net mass 405.0 g, and limiting speed reaches 30000.0 1/min. The cage is designated T, with 2RSD sealing on both sides through non-contact lip seals, and manufacturing falls under restricted tolerances (P4S). The non-contact seal design minimizes friction and heat generation, supporting sustained operation at the stated limiting speed while keeping contamination out of the raceway. Restricted tolerances and the paired/set configuration make this bearing suitable for arrangements requiring tight running accuracy and controlled preload, with the 25° contact angle providing combined radial and axial load carrying capability.
