Description

This combined bearing carries axial and radial loads through an integrated needle roller section paired with an angular contact ball bearing arrangement. Bore diameter is 17.0 mm, outside diameter 30.0 mm, width 18.0 mm, and net mass 52.7 g. The limiting speed is rated at 20600.0 1/min, with a reference speed of 15000.0 1/min. The combined needle roller and angular contact ball bearing design allows radial and axial loads to be taken up within a single, compact envelope, reducing the axial space normally required for separate bearing arrangements. The angular contact ball bearing component supports axial loads from one direction, so mounting orientation must respect the intended load path. Given the stated speed ratings, the bearing suits applications requiring simultaneous radial and one-directional axial support without additional bearing stages.
