This spindle bearing carries a 25° contact angle and is supplied adjusted, in pairs or sets, with a bore of 80.0 mm, an outside diameter of 140.0 mm and a width of 26.0 mm. Net mass is 1.403 kg. The cage is designated T, and the design comes without sealing, so lubricant supply and contamination protection must be arranged externally. The restricted tolerances place this bearing in the P4S accuracy class, matching the running accuracy and stiffness needed for high-speed rotation with minimal radial and axial play. Since it is matched for pair or set mounting, the preload is set through the paired arrangement rather than through a single unit, and the open design allows oil or grease lubrication to be fed directly to the raceways, which is relevant where controlled thermal behavior and precise axial positioning are required.
