This spindle bearing carries a 25° contact angle and is fitted with non-contact lip seals on both sides, keeping contamination out while allowing high-speed operation. Bore diameter is 40.0 mm, outside diameter 68.0 mm, width 15.0 mm, and net mass 187.78 g. The cage is designated T, and the bearing is manufactured to restricted (tightened) tolerances for precise running accuracy. Supplied adjusted, in pairs or sets, this bearing is intended for mounting arrangements requiring matched preload and controlled internal geometry. The restricted tolerance class supports tight radial and axial guidance, while the double-sided sealing protects the raceways without adding contact friction, making it suitable for applications where sustained rotational precision and low-friction operation are required.
