This spindle bearing is a single row angular contact ball bearing with a 15° contact angle, 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 362.4 g. The bearing uses a T cage and is supplied without sealing, built to restricted tolerances under symbol B71916-C-T-P4S-UL. The restricted tolerances and P4S accuracy class allow this bearing to run true at high rotational speeds with minimal radial and axial deviation, which is essential when paired or set-mounted for controlled preload. The 15° contact angle gives a balance between axial and radial load carrying capability, suited to configurations where the bearing set works under combined loading. As it comes without sealing, lubrication and contamination protection must be provided externally, and the T cage supports stable ball guidance at the speeds this design is intended for.
