This angular contact ball bearing transfers combined radial and axial loads in one direction through a single row of balls set at a contact angle. Bore diameter is 40.0 mm, outside diameter 80.0 mm, and width 18.0 mm, with a net mass of 0.367 kg. The bearing uses a TVP cage made of plastic, part of the X-life design line. Limiting speed is rated at 11900.0 1/min, with a reference speed of 8600.0 1/min. The plastic TVP cage keeps friction and mass low, supporting operation at the stated speed values while maintaining stable ball guidance. Single-row angular contact design means the bearing carries axial load in one direction only, so it is typically mounted in pairs when bidirectional axial support is required. As supplied open (without seals or shields), it requires external sealing and a separate lubrication arrangement suited to the operating speed and load direction.
