This spindle bearing has a 30.0 mm bore, 47.0 mm outside diameter, and 9.0 mm width, giving a net mass of 0.055 kg. It is built with a 25° contact angle and a T-type cage, suited for high rotational speeds up to a limiting speed of 60000 1/min. Sealing is provided by 2RSD lip seals on both sides, working in a non-contact arrangement. The bearing is supplied adjusted, in pairs or sets, allowing precise axial positioning when mounted together. Restricted tolerances place it in a high accuracy class, matching the demands of high-speed rotation, while the non-contact lip seals reduce friction and heat generation compared to contact-type sealing, keeping the bearing suitable for applications where low running temperature and precise rotation are required.
