This spindle bearing has a 25° contact angle and is designed for precision mounting as matched pairs or sets. Bore diameter is 95.0 mm, outside diameter 145.0 mm, and width 24.0 mm, with a net mass of 1.292 kg. The cage is made of material T, and the bearing is fitted with non-contact lip seals on both sides (2RSD), keeping friction low while limiting speed to 18000 1/min. Restricted tolerances and P4S accuracy class make this bearing suitable for applications requiring precise shaft guidance under high rotational speed. The non-contact sealing arrangement protects the raceways without adding rotational resistance, while paired mounting allows preload adjustment to control axial and radial stiffness. The construction supports stable operation where thermal expansion and speed-related effects must be tightly controlled.
