This spindle bearing carries a 15° contact angle and is manufactured to restricted (P4S) tolerances for precise running accuracy under high-speed conditions. Bore diameter is 15.0 mm, outside diameter 32.0 mm, width 9.0 mm, and net mass is 32.0 g. The bearing is fitted with a T cage and supplied without sealing. The limiting speed reaches 110000 1/min, reflecting the design intent for high-speed operation. Being of type C, this bearing is matched and supplied in pairs or sets, adjusted to work together under a defined preload, which supports rigidity and consistent axial positioning of the shaft. The absence of sealing means external lubrication and housing protection must be provided by the surrounding assembly. Given the restricted tolerances and cage design, this bearing suits applications where high rotational speed and running accuracy are the governing requirements, with mounting and lubrication arranged to maintain the specified preload condition between the paired bearings.
