This spindle bearing carries a 15° contact angle and is manufactured to restricted tolerances, allowing it to be adjusted and mounted in pairs or sets. Bore diameter is 40.0 mm, outside diameter 68.0 mm, width 15.0 mm, and net mass is 188.97 g. The cage is designated T, and the bearing has no sealing. The P4S accuracy class combined with the restricted tolerances supports precise axial and radial positioning when mounted in matched pairs or sets, which is required for consistent preload across the arrangement. As the bearing is unsealed, lubrication and contamination protection must be provided externally, and the design is intended for arrangements where controlled internal geometry and matched fitting of multiple bearings are required to maintain running accuracy.
