bearings reduce friction by means of rolling motion (reduces friction more than the « plain bearing »). sliding motion allows a greater decrease in the amount of energy consumption during rotation.

  • Bearings are constrained elements used to reduce the friction of certain moving parts in a machine or device.
  • This is done by replacing sliding friction with rolling friction.
  • Bearings are used to provide better linear motion or rotation around a fixed axis.
  • Roller bearings are typically cylinders similar to free rollers, except that they are constrained in their motion.
  • Ball bearings are spheres that are held in a track.
