What are Acme Balls?

An Acme ball, also known as an Acme ball screw, is a specific type of screw. These screws are easy to identify due to the presence of circular threads along both the screw and the nut, forming a kind of helical racetrack for small ball bearings to run along. The ball bearings can move along the track as the screw moves, and this helps to push the screw forward, generating linear motion.

What are Acme Balls Used for?

Ball screws or Acme balls are often used in conjunction with or instead of standard Acme screws in linear motion systems and mechanisms. Thanks to their clever design, ball screws are very efficient, with low levels of frictional loss, due to the presence of the ball bearings in the track. These kinds of screws can achieve efficiency ratings in excess of 90%, generating higher forces and speeds than other alternatives.
