Roller bearing technology

Needle bearings

The circular-cylindrical rollers are very long in relation to the diameter of the rolling element. Thus, they have a very small overall size and are therefore mainly used in gears. With needle roller bearings, an inner ring is often waived.

The advantage of a needle roller bearing comes with its low installation height and its high load-bearing capacity.

The disadvantage of a needle bearing is, compared to other types of rolling bearings, maximum permissible speed is lower due to its smaller size. It is also more susceptible to forces acting contrary to the carry load.
