This spindle bearing carries a 15° contact angle and is designed for adjusted mounting in pairs or sets, allowing it to take up combined radial and axial loads with defined preload. Bore diameter is 20.0 mm, outside diameter 47.0 mm, width 14.0 mm, and net mass is 112.0 g. The cage is coded T, and the bearing is fitted with non-contact lip seals on both sides, keeping friction low while restricting contamination from entering the bearing interior. The restricted tolerances (P4S) give it the running accuracy needed for high-precision, high-speed rotation with minimal radial and axial runout. Being supplied as a matched set with defined preload, it is intended for mounting in pairs to achieve consistent stiffness and load distribution across both bearings. The non-contact seal design permits high-speed operation without added torque, while the C-series internal geometry supports stable performance under the specified contact angle.
