This single row angular contact ball bearing carries axial loads in one direction combined with radial loads, using a contact angle design that requires the mating bearing to be preloaded or paired for bidirectional axial support. Bore diameter is 80.0 mm, outside diameter 170.0 mm, and width 39.0 mm, with a net mass of 3.65 kg. The X-life design provides increased load carrying capacity within the standard envelope dimensions. The cage is a solid plastic cage, designation TVP, guided on the outer ring, contributing to stable ball guidance at higher speeds. Limiting speed is 5200 1/min and reference speed is 4250 1/min, making this bearing suitable for applications running close to these values without additional cooling measures. The plastic cage reduces friction and mass compared to a solid brass cage, allowing smoother operation and lower heat generation at speed. As a single row design, it should be mounted in pairs or combined with another bearing to absorb axial loads from both directions, with shaft and housing tolerances selected according to the required internal clearance and running accuracy.
