Description
This combined bearing carries a needle roller bearing and an angular contact ball bearing arranged together in one unit, with the ball bearing component taking axial loads in both directions. Bore diameter is 20.0 mm, outside diameter 37.0 mm, width 25.0 mm, and net mass is 0.107 kg. Limiting speed is rated at 17200 1/min, with a reference speed of 14000 1/min. The combination design allows simultaneous support of radial load through the needle roller section and axial load in both directions through the angular contact ball bearing section, reducing the axial space needed compared to using separate bearings for these functions. This construction suits arrangements where radial and bidirectional axial loads occur at the same shaft location and where compact axial dimensions are required.
