This spindle bearing is built with a 25° contact angle and a bore of 120.0 mm, outside diameter of 180.0 mm, and width of 28.0 mm, giving a net mass of 2.286 kg. It is fitted with a T cage and 2RSD lip seals on both sides, running non-contact, and manufactured to restricted (P4S) tolerances for adjusted mounting in pairs or sets. The limiting speed is stated at 14000.0 1/min. The non-contact lip seals reduce friction while still limiting contamination ingress, which suits the high-speed operation this bearing is designed for. Supplied for use in matched pairs or sets under axial preload, the restricted P4S tolerance class supports precise shaft location and consistent running accuracy, while the 25° contact angle allows the bearing to carry combined radial and axial loads typical of spindle arrangements.
