This spindle bearing supports high-precision rotation with a 15° contact angle and restricted tolerances for accurate axial and radial guidance under speed. Bore diameter is 100.0 mm, outside diameter 180.0 mm, width 34.0 mm, and net mass 3.265 kg. The bearing uses a T cage and is supplied without sealing. The design is matched and adjusted, intended for mounting in pairs or sets to achieve defined preload and stiffness at the shaft. The restricted tolerance class (P4S) suits applications requiring tight running accuracy and low radial and axial play. As the bearing has no integrated sealing, external sealing and a suitable lubrication method must be provided by the housing design to maintain the required precision and operating temperature.
