A shell type outer ring 2 of a shell type needle roller bearing 1 is formed by a pressing combined with an ironing step, and the lubricating conditions in this ironing step on the outer-diameter ironed surface, which becomes the outer-diameter surface of the outer ring 2, are in a substantially fluid lubricating state so as to restrict the circumferential surface roughness of the inner
Get PriceThe 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.
