How to Select the Right Screw Jack for Your Application

Screw jacks are mechanical devices used to lift and position heavy loads. Operation is manual or fully automated with motor starters, programmable positioning systems, and linear actuator controllers. They are an efficient and versatile alternative to hydraulic jack systems.

Let's look at how screw jacks work, the ways they can be used, and important considerations for selecting the right screw jack system for your needs.

Ball Screws vs. Lead Screws: Which is Right For Your Screw Jack Application?

Ball Screws

Screw-driven jacks are the most popular devices used to convert the rotary motion of a motor into linear movement. However, there are two common types of screw-driven systems to choose from: ball screws and lead screws. In this blog, we’ll cover the benefits, drawbacks, and applications of both ball and lead screws to help you determine which option is best for your needs.

Understanding the Differences Between ACME, Ball, and Roller Screw Jacks

A screw jack is known by many names — machine screw jack, worm screw jack, lead screw jack, or jack screw — but it has one primary purpose: to take rotational motion and transform it into linear motion. These products allow you to efficiently lift, lower, push, pull, tilt, hold, or otherwise position a load as heavy as 250 tons. Screw jacks' reliability and capacity for synchronization surpass that of comparable alternatives, facilitating a variety of mechanical applications.
