This spindle bearing has a bore diameter of 10.0 mm, an outside diameter of 22.0 mm, and a width of 6.0 mm, with a net mass of 11.0 g. The design uses a 15° contact angle, a T-type cage, and 2RSD lip seals fitted on both sides, running non-contact. The limiting speed is 160000 1/min, and the bearing is manufactured to restricted tolerances, matched and supplied adjusted, in pairs or sets. The 15° contact angle combined with the light T cage supports stable operation at the stated high limiting speed. The non-contact lip seals on both sides keep friction low while still preventing contaminants from entering the raceway area, which suits applications where minimal heat generation matters. Supply in matched pairs or sets with restricted tolerances allows mounting in back-to-back or face-to-face arrangements without additional selective fitting, maintaining consistent internal clearance across the set.
