This angular contact ball bearing transfers combined radial and axial loads through a single row of balls set at a defined contact angle. It has a bore diameter of 15.0 mm, outside diameter of 35.0 mm, and width of 11.0 mm, with a net mass of 0.044 kg. The X-life design increases internal geometry precision compared to standard versions, and the bearing is fitted with a TVP polyamide cage. Limiting speed is rated at 29500 1/min, with a reference speed of 19100 1/min. The polyamide cage reduces friction and mass compared to steel cages, supporting stable ball guidance at the rated speeds. As a single-row angular contact design, it is intended for mounting in pairs or sets where axial positioning in one direction is required, and its X-life geometry allows higher load ratings within the same envelope dimensions as standard 72-series bearings. The bearing is supplied open, without integrated sealing, so lubrication and contamination protection must be provided by the housing design.
