This spindle bearing carries a 15° contact angle and is designed for precise angular positioning under axial and combined loads. Bore diameter is 30.0 mm, outside diameter 55.0 mm, width 13.0 mm, with a net mass of 0.13 kg. The limiting speed reaches 56000 1/min, supported by a T cage and 2RSD lip seals on both sides, running non-contact for reduced friction. Manufactured to restricted (P4S) tolerances, this bearing is supplied adjusted, in pairs or sets, allowing accurate preload control when mounted back-to-back or face-to-face. The non-contact sealing arrangement limits friction and heat generation, supporting sustained operation at high rotational speed while maintaining consistent running accuracy and low internal clearance.
