Ball screws convert rotary motion to linear motion, or torque to thrust, and vice versa. They are primarily a power screw with a train of ball bearings riding between the screw and the nut in a recirculating track. The screw has a rounded shape to conform to the balls. Ball screws have a predictable service life and low wear rate.  ACME screws and other lead screws transmit torque into linear motion through direct sliding friction. A lead screw device is very similar to a regular nut and bolt combination. Typically, the assembly comes complete with a screw, nut, and bearing support. For low speed and high accuracy applications acme screws are cost effective.

Choices for manufacturing process for ball screws, lead screws, and ACME screws include rolled, milled, or ground.  Rolled screws are cold rolled from a blank. Typically, this produces a screw with a .004 inch per foot accuracy.  Milled screws are made on a milling machine using a cutter with an Acme form. Typically, this produces a screw with a .002 inch per foot accuracy.  Ground screws are made on a grinding wheel with an Acme form. Typically, this produces a screw with .0005 inch per foot lead accuracy.  Important physical specifications to consider when searching for ball screws, lead screws, and ACME screws include design arrangement, length, outer diameter of the screw, screw lead, screw lead accuracy, dynamic load rating, and maximum static load capacity.  The design arrangement can be English or metric.  Some suppliers specify both.  The length of the screw is the most important dimension to consider.  The outer screw diameter is the largest diameter value of the screw.  Screw lead is the axial distance a screw travels during one revolution, measured in inch/turn.  Screw lead accuracy is represented as a percentage.  The dynamic load rating is the load that can be sustained while the assembly is moving.  The maximum static capacity is the load that can be sustained, measured while the load is stationary.
