This single row angular contact ball bearing carries axial loads in one direction combined with radial loads, using a contact angle design that positions raceways at an offset to the bearing axis. Bore diameter is 55.0 mm, outside diameter 100.0 mm, width 21.0 mm, and net mass 0.605 kg. The X-life design provides raceway and rolling element geometry optimized within standard envelope dimensions. The cage is a TVP type, made of glass-fiber reinforced plastic, which reduces mass and friction compared to solid cages. Limiting speed reaches 9200 1/min, with a reference speed of 6800 1/min under standard operating conditions. Due to its single-direction axial load capacity, this bearing is typically mounted in pairs for bidirectional axial support or matched sets requiring defined preload. The plastic cage design allows smooth cage guidance and stable operation at the stated speed range, making the bearing suitable for applications where axial positioning accuracy and moderate to high rotational speeds are required.
