This single row angular contact ball bearing carries a bore of 15.0 mm, outside diameter of 42.0 mm, and width of 13.0 mm, weighing 0.082 kg. It is built to X-life standard, giving increased load carrying capacity within the same envelope dimensions, and uses a TVP plastic cage for reduced friction and stable ball guidance. Limiting speed reaches 24400 1/min, with a reference speed of 14200 1/min. The angular contact design allows the bearing to take combined radial and axial loads acting in one direction, so it is typically mounted in pairs or sets against a mating bearing to handle load in both axial directions. The plastic cage construction supports smooth running at the stated speed ratings and lower operating noise compared to metal cage designs. As supplied open, without integrated sealing, lubrication and protection against contamination must be arranged in the housing design.
