Roller Bearings - an overview | ScienceDirect Topics

Ball bearing and roller bearings are often called antifriction bearings, because the contact between the bearing element is rolling instead of sliding, as in the case of a plain or journal bearing. The area covered by the rolling element is quite less compared to sliding bearings, or we can say that rolling friction is less compared to sliding friction.
