Elephant Racing • Needle Bearing Suspension: Right idea

The result is dry bearing contact points and accelerated race wear in a hill-and-valley pattern. This process is known as false brinelling or fretting. Once false brinelling develops, friction of the roller bearing goes up. In contrast, bronze bearings maintain full contact with the race and deliver even wear for small and large angular rotations.

Needle Roller Bearings Selection Guide

The needle rollers are the load-carrying components of the needle roller bearing. They are located between two races, between a single race and a shaft, or between a shaft and a housing, depending on the design of the bearing. The rolling elements of a needle roller bearing have a large load-bearing surface, but a small diameter.
