This single row angular contact ball bearing carries axial loads in one direction combined with radial loads, using a contact angle design that requires paired or opposed mounting for bidirectional axial support. Bore diameter is 40.0 mm, outside diameter 90.0 mm, width 23.0 mm, and net mass 0.616 kg. The X-life design provides increased load rating within standard boundary dimensions. Limiting speed is 10400 1/min, with a reference speed of 7100 1/min. The cage is of TVP type, made of plastic, running centered on the balls, which supports smooth operation at higher speeds and reduces friction losses compared to solid cage designs. The bearing is supplied without seals or shields, so lubrication and contamination protection must be provided by the housing arrangement. Its angular contact geometry and X-life construction make it suitable for applications where combined loading and precise axial positioning under single-direction thrust are required.
