This spindle bearing is designed for precision applications requiring high rotational speed capability, featuring a 25° contact angle and ceramic balls that reduce rolling mass and centrifugal loading. Bore diameter is 55.0 mm, outside diameter 90.0 mm, width 18.0 mm, with a net mass of 0.386 kg. The cage is designated T, and the bearing carries P4S accuracy class with restricted tolerances suited for precise shaft positioning. Sealing type 2RSD provides non-contact lip seals on both sides, protecting the bearing interior while keeping frictional losses low at speed. Supplied for mounting in pairs or sets and pre-adjusted at the factory, this bearing suits arrangements where matched preload and consistent internal clearance are required across the set. The construction supports stable running accuracy under the specified tolerance class, making it suitable for shaft support where axial and radial precision must be maintained together.
