This combined bearing integrates a needle roller bearing with an angular contact ball bearing, giving it a bore of 15.0 mm, an outside diameter of 28.0 mm, and a width of 20.0 mm. Net mass is 50.89 g. The limiting speed is 21600 1/min, with a reference speed of 17000 1/min. The angular contact ball bearing component supports axial loads in both directions, allowing the unit to handle combined radial and bidirectional axial loading within a compact envelope. This design suits arrangements where radial and axial guidance must be combined in a single position without adding extra axial length, reducing the need for a separate axial bearing.
