This is a single row angular contact ball bearing designed to carry combined radial and axial loads in one direction, with a contact angle that allows higher axial load capacity than standard radial ball bearings. Bore diameter is 17.0 mm, outside diameter 40.0 mm, width 12.0 mm, and net mass is 0.066 kg. The bearing uses a sheet metal cage (JP) and belongs to the X-life design line, offering a limiting speed of 26000 1/min and a reference speed of 17100 1/min. The single-row angular contact design means this bearing should be mounted in pairs or combined with a second bearing when axial loads act in both directions, since it only supports axial thrust from one side. The sheet metal cage reduces mass and friction, supporting the higher limiting speed, making the bearing suitable for applications requiring stable operation at elevated rotational speeds with combined load conditions.
