Bearings: Tribological Components | GGB

Bearings are tribological components that carry a load while in contact with and moving relative to another part. The movement may be sliding or rotating. There are basically two different types of bearings: plain bearings and roller bearings. Other types include fluid bearings that support their loads on a thin layer of gas or liquid; magnetic

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.
