This spindle bearing has a 25° contact angle and is designed for precise angular positioning under combined axial and radial loads. Bore diameter is 25.0 mm, outside diameter 42.0 mm, width 9.0 mm, and net mass 50.0 g. The cage is marked T, and the bearing is fitted with non-contact lip seals on both sides (2RSD). Limiting speed reaches 67000 1/min. Manufactured to restricted tolerances (P4S) for high-precision applications, this bearing is intended for use in matched pairs or sets, allowing correct preload and stiffness through adjustment. The non-contact sealing arrangement minimizes friction and heat generation, supporting stable operation at high rotational speeds while maintaining protection against contamination.
