This spindle bearing carries a 15° contact angle and is designed for adjusted mounting in pairs or sets. Bore diameter is 12.0 mm, outside diameter 24.0 mm, width 6.0 mm, with a net mass of 20.0 g. The cage is designated T, and the bearing operates without sealing, restricted tolerances apply per the C designation, with P4S accuracy class and UL suffix indicating the specific internal configuration. The restricted tolerances and P4S accuracy class support precise shaft guidance under high-speed rotation, while the 15° contact angle allows the bearing to handle combined axial and radial loads when mounted in pairs or sets for preload control. As the bearing has no integrated sealing, external protection against contamination must be provided, and lubrication should be selected and applied according to the operating conditions of the specific spindle assembly. The T cage design supports the arrangement typical of this bearing series.
