This single row angular contact ball bearing carries balls arranged to support combined radial and axial loads in one direction, with a defined contact angle giving it stiffness under axial preload. Bore diameter is 20.0 mm, outside diameter 42.0 mm, width 12.0 mm, and net mass is 60.0 g. It runs with a plastic cage (TVP), part of the X-life design line. Limiting speed is rated at 22600 1/min, with a reference speed of 14400 1/min. The plastic TVP cage reduces friction and mass compared to a metal cage, supporting stable guidance of the balls at the stated speed range and contributing to smooth running under angular contact loading. As a single row design, it is intended for mounting in pairs or sets where axial loads act in a defined direction, and the X-life manufacturing standard indicates tighter geometric consistency of the rolling elements for the given bore and outside diameter.
