This spindle bearing is designed for high-precision rotation at elevated speeds, with a bore diameter of 100.0 mm, outside diameter of 140.0 mm and width of 20.0 mm. It has a 25° contact angle, a T-type cage, and non-contact lip seals on both sides (2RSD). Net mass is 0.851 kg, and the limiting speed reaches 18000 1/min. Manufactured to restricted tolerances (P4S) and supplied adjusted, in pairs or sets, this bearing suits applications requiring precise axial and radial positioning under high rotational speed. The non-contact sealing reduces friction and heat generation, supporting stable operation at the specified speed limit, while the defined contact angle allows combined radial and axial load handling within a rigid, low-clearance arrangement.
