This spindle bearing carries a 25° contact angle and is designed for precision arrangement in pairs or sets. Bore diameter is 12.0 mm, outside diameter 24.0 mm, width 6.0 mm, and net mass is 13.0 g. The limiting speed reaches 130000 1/min, the cage is made in T version, and sealing is provided by non-contact lip seals on both sides (2RSD), keeping lubricant in and contaminants out without adding friction. Manufactured to restricted (P4S) tolerances, this bearing suits precision shaft mounting where accurate running and low internal clearance are required at high rotational speed. The non-contact seal design supports the high limiting speed by minimizing drag, while the T cage contributes to stable ball guidance under these conditions. Suitability for adjusted pair or set mounting allows preload control matched to the required stiffness and accuracy of the shaft arrangement.
