Bushing or Bearing, what’s the difference?

Jan 15, 2021· Ball Bearings. Ceramic or steel balls are fitted between inner and outer rings to create the classic ball bearing. These are designed to support rotating shafts, while reducing friction between the static and moving parts. Ball bearings support rotating shafts while cutting down on the fraction between these and static components.
