This single row angular contact ball bearing carries axial loads in one direction combined with radial loads, using a contact angle design that requires an opposing bearing for full shaft support. It has a bore diameter of 80.0 mm, outside diameter of 140.0 mm, and width of 26.0 mm, with a net mass of 1.42 kg. The X-life design provides increased load carrying capacity within standard boundary dimensions. The bearing is fitted with a plastic cage (TVP), positioning the rolling elements and reducing friction and heat generation at speed. Limiting speed is rated at 6400 1/min and reference speed at 4950 1/min, indicating suitable operation under sustained radial and one-directional axial loading in applications with moderate to high rotational speed. The single row configuration and defined contact angle make it suitable for mounting in pairs to accommodate combined loads and to control axial positioning, while the plastic cage supports smooth operation under grease lubrication.
