This spindle bearing supports precise rotation at a 25° contact angle, with a bore diameter of 17.0 mm, outside diameter of 40.0 mm, and width of 12.0 mm, weighing 65.0 g net. It features a T cage and non-contact lip seals on both sides, and is supplied adjusted, in pairs or sets, to restricted tolerances (P4S). The paired/set adjustment and restricted tolerance class allow this bearing to maintain accurate axial and radial positioning under combined loads at the 25° contact angle, while the non-contact lip seals on both sides keep contamination out without adding friction. This configuration suits mounting arrangements requiring controlled preload and high running accuracy.
