  • Bushing or Bearing, what’s the difference?

    2021-1-15 · There isn’t really a difference: a bushing is a type of bearing. In general, a “bearing” facilitates movement between two parts while reducing friction. Simple in design, the typical bearing has two surfaces that roll over each other, enabling two mating components to move friction-lessly.
