This spindle bearing carries a 15° contact angle and is supplied adjusted, in pairs or sets, with a bore of 110.0 mm, outside diameter of 170.0 mm and width of 28.0 mm. Net mass is 1.982 kg. The cage is designated T, and the bearing is manufactured to restricted tolerances (P4S), which corresponds to high running accuracy suited to precision shaft support. No sealing is fitted. The restricted tolerance class and paired/set arrangement allow this bearing to take up combined radial and axial loads with defined preload and minimal internal play, which is required for precise shaft guidance under high rotational speed. As the bearing is unsealed, external sealing arrangement and separate lubrication supply must be provided by the housing design. Matched sets should be mounted together and not interchanged with bearings from other sets to preserve the preload and running accuracy.
