This spindle bearing carries a 15° contact angle and is designed for adjusted mounting in pairs or sets. Bore diameter is 120.0 mm, outside diameter 180.0 mm, width 28.0 mm, and net mass is 2.07 kg. It is fitted with a T cage and has no sealing arrangement, corresponding to the B70..-C design with restricted tolerances (P4S). The restricted tolerances and paired/set arrangement allow precise axial and radial positioning under combined loading, making this bearing suitable for applications requiring high rotational accuracy. Since sealing is absent, external protection and lubrication management must be handled by the housing design. The T cage supports stable rolling element guidance at the specified contact angle, and the C design permits controlled preload when mounted as a matched pair or set.
