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

Rolling Bearings - an overview | ScienceDirect Topics

The rolling elements, balls, rollers, or needles divide the bearing rings. The rolling bearings operate at lower starting friction with a coefficient of friction of μ = 0.001 – 0.003. Other advantages are easy lubriion and replacement in case of failure. Some disadvantages of rolling bearings are collapse to large loads, higher costs, and
