This spindle bearing carries a 15° contact angle and is manufactured to restricted tolerances for precision alignment under axial and radial combined loads. Bore diameter is 100.0 mm, outside diameter 150.0 mm, width 24.0 mm, and net mass 1.24 kg. The cage is designated T, and the bearing is supplied without sealing, adjusted for use in pairs or sets to achieve a defined internal setting. The P4S accuracy class supports high rotational precision and running consistency required in spindle applications. As the bearing has no integrated sealing, external sealing and lubrication provisions must be arranged by the housing design. Pairing or set arrangement allows control of preload, which stabilizes stiffness and reduces axial play during operation.
