Description
This angular contact ball bearing carries combined radial and axial loads in one direction, with a single row of balls set at a defined contact angle for stiff axial support of the shaft. Bore diameter is 55.0 mm, outside diameter 120.0 mm, width 29.0 mm, and net mass 1.53 kg. The design is part of the X-life series, using a solid brass cage (MP) that guides the balls precisely and withstands higher operating temperatures and centrifugal loads at speed. The bearing is rated for a limiting speed of 10000 1/min and a reference speed of 5600 1/min, making it suitable for shaft arrangements requiring stable running at elevated rotational speeds. As a single-row angular contact design, it should be mounted in pairs or in combination with another bearing to accommodate axial loads acting in the opposite direction. The solid brass cage improves guidance accuracy and reduces cage wear compared with pressed steel cages, supporting consistent performance under sustained speed and load.
