This single row angular contact ball bearing carries axial and radial loads in one direction, with the raceway geometry setting a defined contact angle between rings and balls. Bore diameter is 80.0 mm, outside diameter 170.0 mm, width 39.0 mm, and net mass 3.65 kg. The bearing is built on the X-life design, giving increased load rating within standard boundary dimensions. It runs on a TVP cage made of plastic, which reduces friction and mass compared to a machined cage while keeping the balls evenly spaced through the load zone. Limiting speed is 5200 1/min and reference speed 4250 1/min, so the bearing suits arrangements running close to these thresholds without exceeding thermal limits. As a single row angular contact ball bearing, it is normally mounted in pairs or sets when loads act in both axial directions, and the design tolerates only slight shaft misalignment. No integrated seal is specified, so relubrication and external sealing must be arranged according to the operating environment.
