This spindle bearing is designed for precision high-speed applications, with a bore diameter of 17.0 mm, outside diameter of 35.0 mm, and width of 10.0 mm, weighing 45.0 g. It has a contact angle of 25° and is fitted with a polymer cage (T). Sealing is provided by non-contact lip seals on both sides (2RSD), and the limiting speed reaches 85000 1/min. Supplied adjusted, in pairs or sets, this bearing is manufactured to restricted (P4S) tolerances, allowing precise axial and radial positioning when mounted as a matched set. The non-contact seal arrangement reduces friction and heat generation at high rotational speeds, while the defined contact angle supports combined radial and axial loading. The restricted tolerance class and matched-set supply ensure consistent preload and running accuracy once installed.
