Bearings have been in every day life for years

If you think about it; more than 4500 years ago, Egyptians used cylindrical rollers to move large heavy blocks of stone need for pyramids, preempting the use of ball bearings.

Similar usage was done in the creation of Stonehenge years later.

Leonardo de Vinci discovered the principle of the bearing in the 15th century. He realized that friction could be reduced if the balls did not touch each other. With this realization he designed separators allowing the balls to move freely. This design was reinvented in the 18th century when a horse carriage axle fitted with a ring of balls rolling in semi-circular grooves made in teh axle was patented in England.



Bearings have been a part of every day life for years.

Computers have bearings in the hard drives.
Exercise equipment is equipped with various bearings

Ball bearings are used in daily objects such as:


  •     electric guitars
  •     bicycles
  •     video game controllers
  •     blenders
  •     camcorders
  •     garage door openers
  •     hot tubs
  •     aquarium water pumps and aerators
  •     roll and in line skates
  •     cellphones


Yes — even Cellphones .. What makes the phone vibrate.  The phone vibrates from a tiny motor — which uses bearings in which to run.

The Hubble telescope and weather satellites are classic examples of ball bearings as part of the highest technology.
