Q: What is the difference between a acme screw jack and a ball screw jack?
A: Acme screw jack uses an acme threaded screw that is typically self-locking, meaning it will hold its position without a brake. Ball screw jacks use ball screws to convert rotary motion to linear movement, and require 1/3 the horsepower compared to a acme screw jack. Due to the efficiency of the ball screw, brakes must be used to stop and hold the load screw in position. Brakes are also recommended for use on any jacks if vibration is present.
