This spindle bearing is designed for precision rotation at a 25° contact angle, using ceramic balls and a T-type cage. Bore diameter is 70.0 mm, outside diameter 100.0 mm, width 16.0 mm, and net mass 0.332 kg. Sealing is provided by 2RSD lip seals fitted on both sides, running without contact against the mating surface. The P4S accuracy class and restricted tolerances make this bearing suitable for arrangements requiring tight running precision, matched in pairs or sets for defined preload. The non-contact lip seals limit friction and heat generation while still protecting against contamination, which supports stable operation at high rotational speeds. The E design variant increases load carrying capacity within the given envelope dimensions.
