Description

This spindle bearing is a single-row angular contact design with a 15° contact angle, built for precision pairing and preload adjustment. Bore diameter is 20.0 mm, outside diameter 37.0 mm, width 9.0 mm, and net mass 0.039 kg. It is fitted with a T cage and non-contact lip seals on both sides, sealing the bearing while keeping friction low. The restricted (P4S) tolerance class and the C contact angle variant make this bearing suitable for mounting in matched pairs or sets under defined preload, supporting accurate shaft guidance at high rotational speeds. The non-contact lip seals protect the raceways without adding running torque, while the T cage design supports stable rolling element guidance under the specified contact angle. Grease or oil lubrication compatible with the sealing arrangement should be selected according to the operating speed and preload condition applied during mounting.
