This spindle bearing carries a 15° contact angle and is manufactured to restricted (P4S) tolerances, allowing it to be matched in pairs or sets with consistent preload behavior. Bore diameter is 20.0 mm, outside diameter 42.0 mm, width 12.0 mm, and net mass is 0.07 kg. The cage is designated T, and the bearing is supplied without sealing. The restricted tolerances and defined contact angle make this bearing suitable for arrangements requiring precise axial and radial guidance under controlled preload, typically set up in back-to-back or face-to-face pairs to balance combined loads. As it has no integrated seal, external sealing and a separate lubrication system must be provided; the T cage supports stable roller guidance at the precision level this design is built for.
