This spindle bearing carries a 15° contact angle and is manufactured to restricted tolerances, allowing it to run true at high rotational speeds. Bore diameter is 100.0 mm, outside diameter 150.0 mm, width 24.0 mm, and net mass 1.299 kg. The limiting speed is rated at 19000 1/min. The cage is designated T, and the bearing is supplied without sealing. The HS7020-C-T-P4S-UL is matched and supplied in pairs or sets, so mounting requires maintaining the factory-set preload rather than treating it as a standalone single bearing. The P4S accuracy class and the restricted tolerance grade give it the running precision needed for stable operation at the stated speed limit, while the absence of seals means lubrication and contamination protection must be provided by the housing arrangement. Since it is unsealed, external lubrication (oil) suited for high-speed operation is required, and clean running conditions must be maintained around the bearing position.
