This angular contact ball bearing transmits combined radial and axial loads through a single row of balls set at a defined contact angle, supported on a steel sheet metal cage (JP design). Bore diameter is 40.0 mm, outside diameter 80.0 mm, width 18.0 mm, and net mass 386.0 g. The X-life design provides increased load carrying capacity within standard boundary dimensions. Limiting speed is rated at 11900 1/min, with a reference speed of 8600 1/min. The single-row contact angle design allows the bearing to carry axial loads in one direction only, so mounting in pairs is required where axial loads act in both directions or where a defined bearing arrangement with controlled preload is needed. The steel sheet metal cage keeps the ball set guided at higher speeds while limiting cage mass, supporting operation up to the stated limiting and reference speed values. As supplied without seals or shields, lubrication and contamination protection must be provided by the surrounding housing design.
