This combined bearing carries axial and radial loads through a needle roller section paired with an angular contact ball bearing arranged within a single unit, bore 15.0 mm, outside diameter 28.0 mm, width 18.0 mm, mass 48.42 g. Limiting speed is 21600 1/min, reference speed 17000 1/min. The needle roller component takes up radial forces while the angular contact ball bearing section absorbs axial loads acting in one direction, so the design suits mounting positions where both load types occur on a compact axial length without stacking separate bearings. Correct axial preload and adequate lubrication at the roller and ball raceways are needed to reach the stated speed ratings.
