This spindle bearing carries a 25° contact angle and is fitted with non-contact lip seals on both sides (2RSD), a design that keeps friction low while still limiting contamination ingress at the raceways. Bore diameter is 20.0 mm, outside diameter 37.0 mm, width 9.0 mm, and net mass is 45.9 g. The cage is executed in version T, and the limiting speed reaches 80000.0 1/min, reflecting the precision geometry required for high-speed rotation. Manufactured to restricted (P4S) tolerances, the bearing is supplied adjusted, in pairs or sets, so it can be mounted back-to-back, face-to-face, or in tandem to achieve a defined preload without additional matching on site. The 25° contact angle gives combined radial and axial load capacity, while the non-contact seals avoid added torque, keeping the bearing suited to sustained high-speed operation where running accuracy and low heat generation are decisive.
