This spindle bearing is designed for high rotational speeds, with a contact angle of 25° and a bore diameter of 35.0 mm, outside diameter of 55.0 mm, and width of 10.0 mm. It has a net mass of 0.079 kg and a limiting speed of 50000 1/min. The bearing features a T cage and 2RSD sealing on both sides, non-contact lip seals that keep out contamination without adding friction. Supplied adjusted, in pairs or sets, this spindle bearing suits mounting arrangements requiring precise axial and radial positioning under restricted tolerances. The non-contact seal design supports operation at the stated limiting speed while maintaining protection against dust ingress, and the paired configuration allows for consistent preload across the bearing set.
