This spindle bearing carries a 25° contact angle and is designed for precise axial and radial location under combined loading. Bore diameter is 100.0 mm, outside diameter 150.0 mm, width 24.0 mm, and net mass 1.24 kg. The bearing uses a T cage and is supplied without sealing, matched for mounting in pairs or sets with restricted tolerances (P4S). The restricted tolerance class and matched-set design allow accurate control of internal clearance when the bearings are paired, supporting stable running accuracy at high rotational speeds. As sealing is not provided, external protection or a separate sealing arrangement must be foreseen, and lubrication must be selected and supplied according to the operating conditions of the application.
