This spindle bearing is a single row angular contact design with a contact angle of 15°, intended for adjusted mounting in pairs or sets. Bore diameter is 60.0 mm, outside diameter is 85.0 mm, and width is 13.0 mm, giving a narrow cross-section suited for compact housing arrangements. Net mass is 183.4 g. The cage is of type T, and the bearing is produced to restricted tolerances under symbol B71912-C-T-P4S-UL, matching the series B719..-C construction. The restricted tolerances and P4S accuracy class allow precise axial and radial positioning when the bearing is paired or set-mounted, which is required to maintain the fixed 15° contact angle under load. The absence of sealing means lubrication and contamination protection must be provided externally, typically through the housing design or a closed-loop lubrication system. As the bearing is supplied without integrated sealing elements, mounting should account for consistent, clean lubrication delivery to preserve the running accuracy expected from this tolerance grade.
