Description
This spindle bearing carries a 15° contact angle and is designed for adjusted mounting in pairs or sets. Bore diameter is 25.0 mm, outside diameter 42.0 mm, width 9.0 mm, and net mass 43.93 g. It uses a T cage and has restricted tolerances, matching the P4S accuracy class marked on the symbol. The 15° contact angle allows combined radial and axial load support with high stiffness, suited to arrangements requiring precise axial positioning through paired or set mounting. The restricted tolerances and P4S class support high running accuracy at elevated speeds. As the bearing has no sealing, external protection and a separate lubrication supply must be provided by the housing design; the C designation indicates the specific internal geometry variant for this adjusted configuration.
