This spindle bearing is designed for precise high-speed rotation, with a 15° contact angle and a bore diameter of 45.0 mm, outside diameter of 68.0 mm, and width of 12.0 mm. It has a net mass of 0.14 kg and a limiting speed of 43000 1/min. The cage is made of T material, and sealing is provided by 2RSD lip seals on both sides, which are non-contact. Supplied adjusted, in pairs or sets, this bearing operates under restricted tolerances (P4S), making it suitable for applications requiring high precision and stability at elevated rotational speeds. The non-contact sealing design minimizes friction, contributing to efficient performance and reduced heat generation during operation. Its construction supports demanding rotational requirements while maintaining accuracy in alignment and operation.
