This single-row angular contact ball bearing carries loads at a defined contact angle, allowing it to take up combined radial and axial loads in one direction. Bore diameter is 45.0 mm, outside diameter 85.0 mm, and width 19.0 mm, with a net mass of 0.428 kg. The cage is a steel sheet metal design (JP), and the bearing belongs to the X-life series, which provides tighter internal geometry tolerances than standard execution. Limiting speed reaches 11000 1/min, with a reference speed of 8000 1/min, making this bearing suitable for shafts requiring stable axial positioning under moderate to high rotational speeds. Since it is a single-row angular contact design, two bearings are typically arranged in pairs to support axial loads acting in both directions. The steel cage construction supports reliable ball guidance and consistent operation under grease lubrication.
