This single row angular contact ball bearing carries balls positioned at a defined contact angle, allowing it to take up combined radial and axial loads acting in one direction. Bore diameter is 50.0 mm, outside diameter 90.0 mm, width 20.0 mm, and net mass is 0.47 kg. The bearing uses a steel sheet metal cage, designated JP, which reduces mass and friction compared to solid cage designs. Limiting speed is rated at 10300.0 1/min, with a reference speed of 7600.0 1/min, reflecting the X-life design line. The angular contact geometry means this bearing should be mounted in pairs or in combination with another bearing capable of taking axial load from the opposite direction, since it only supports thrust one way. The steel sheet metal cage keeps rotating mass low, supporting the stated speed ratings, while the X-life manufacturing standard indicates tighter internal geometry control for smoother running at the given bore and outside diameter. No sealing or lubrication is specified, so relubrication and contamination protection must be arranged externally according to the operating conditions.
