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
