This is a single row angular contact ball bearing that carries combined loads by transmitting radial and axial forces through the contact angle between the raceways and balls. It has a bore diameter of 45.0 mm, outside diameter of 100.0 mm, width of 25.0 mm, and a net mass of 0.81 kg. The bearing uses a TVP plastic cage from the X-life series, which positions the balls precisely and reduces friction losses during rotation. The design supports a limiting speed of 9300 1/min and a reference speed of 6500 1/min, making it suitable for applications requiring stable performance at elevated rotational speeds. The single row angular contact configuration allows the bearing to handle axial loads in one direction combined with radial loads, and it is typically mounted in pairs when bidirectional axial loading is present. The plastic cage construction contributes to smooth operation and reduced heat generation compared to designs with heavier cage materials, supporting consistent performance under the specified speed ratings.
