This single row angular contact ball bearing transmits combined radial and axial loads in one direction, with contact angle design supporting axial thrust. Bore diameter is 55.0 mm, outside diameter 120.0 mm, and width 29.0 mm, giving a net mass of 1.41 kg. The bearing uses a steel sheet metal cage (JP) and belongs to the X-life series with a limiting speed of 7700.0 1/min and reference speed of 5600.0 1/min. The pressed steel cage design keeps mass low while maintaining guidance accuracy at the stated speed ratings, making the bearing suitable for applications requiring high rotational speeds combined with defined axial load capacity in one direction. As a single row angular contact type, mounting typically pairs it with a second bearing to accommodate axial loads from both directions or to provide adjusted preload. The X-life designation indicates optimized internal geometry for extended service life under rated load and speed conditions.
