Description
This spindle bearing has a 25° contact angle and is supplied adjusted, in pairs or sets, for mounting in defined arrangements. Bore diameter is 17.0 mm, outside diameter 30.0 mm, width 7.0 mm, and net mass is 22.0 g. The cage is designated T, sealing is 2RSD with non-contact lip seals on both sides, and the limiting speed is rated at 95000 1/min. Tolerances are restricted to suit precision spindle applications. The non-contact seal design keeps friction and heat generation low, supporting the high limiting speed while still providing protection against contamination. Restricted tolerances and the P4S accuracy class allow accurate, low-runout mounting, and supply as matched pairs or sets makes the bearing suitable for arrangements requiring defined preload and controlled axial positioning under the given contact angle.
