SKF Needle roller bearing without ribs without inner ring Series: RNAO

Needle roller bearings without ribs on the outer ring are ready-to-fit units. The bearings are not self-retaining. This means that the outer ring, needle roller and cage assembly and inner ring can be fitted independently of each other. Needle roller bearings without ribs on the outer ring are available with and without an inner ring in a single or double row design. Bearings without an inner ring are highly suitable for bearing arrangements with particularly compact radial dimensions, if the shaft raceway can be hardened and ground.
