Provides angular contact support for high-precision rotating shafts, with a 25° contact angle and a bore of 90.0 mm, outside diameter of 125.0 mm and width of 18.0 mm. The bearing is built with a T cage and has no sealing, giving a net mass of 0.546 kg. Restricted tolerances apply to this design, matching the requirements of the P4S accuracy class, and the design corresponds to the UL designation. This spindle bearing is supplied adjusted, in pairs or sets, allowing mounting in back-to-back, face-to-face or tandem arrangements depending on the required stiffness and load direction. The 25° contact angle makes it suitable for combined radial and axial loads with high running accuracy, while the P4S tolerance class ensures the geometric precision needed for high-speed rotation. As the bearing has no integrated sealing, external sealing and a suitable lubrication method must be provided by the housing arrangement.
