Needle roller bearings

Needle roller bearings are standardised anti-friction bearings in accordance with DIN 616 to 618 and are similar to the cylinder roller bearings (DIN 5412), but have not emerged from the latter historically. This is why needle roller bearings should not be designated as cylinder roller bearings.

NadellagerThe cylindrical needles that serve as rolling elements have a large length in relation to their diameter. This is why they have a very low installation size and hence are used frequently in gearboxes. Differentiation is made between the various designs:

- Needle roller assembly, one roller element cage with roller elements without an external housing

- Needle roller bearings without an inner ring require a hardened contact surface on the shaft

- Needle roller bearings with inner ring
