This single row angular contact ball bearing carries balls arranged at a defined contact angle within a steel sheet metal cage (JP design), enabling combined radial and axial load transmission in one direction. Bore diameter is 25.0 mm, outside diameter 52.0 mm, and width 15.0 mm, with a net mass of 137.0 g. The X-life design raises load carrying capacity within the standard envelope dimensions. Limiting speed reaches 19200 1/min, with a reference speed of 13700 1/min. The single-direction contact angle means this bearing should be mounted in pairs or combined with a second angular contact bearing to support axial loads acting in both directions. The steel sheet metal cage keeps mass low and allows stable ball guidance at higher speeds, matching the stated limiting and reference speed values. As supplied without integrated sealing, lubrication and contamination protection must be provided by the housing design, and mounting should maintain the correct preload to keep radial and axial stiffness within the intended working range.
