This spindle bearing carries a 25° contact angle and is designed for precise axial and radial guidance in pairs or sets, with matched faces allowing exact preload adjustment. Bore diameter is 40.0 mm, outside diameter 68.0 mm, width 15.0 mm, and net mass is 0.209 kg. The limiting speed reaches 40000 1/min, supported by a T cage construction. Sealing is provided by non-contact lip seals on both sides (2RSD), keeping friction low at high rotational speeds. The P4S accuracy class and restricted tolerances make this bearing suitable for applications requiring tight running accuracy and controlled preload under high-speed conditions. The non-contact seal design minimizes heat generation while still limiting contaminant ingress, which supports stable operation at sustained high speeds. Being supplied as matched sets, correct orientation and mounting according to the set marking is required to maintain the intended preload and rigidity.
