A manual ball screw jack is a mechanical device that is used for lifting heavy loads. It is a popular choice for applications such as industrial machinery and material handling systems. In this guide, we will take a closer look at this amazing engineering feat, exploring its uses, working principle, differences from hydraulic jacks, and how to choose the right one for your needs.

What is a screw jack used for?

A screw jack is used for lifting, lowering, pushing, or pulling heavy loads. Here are some of its common applications:

  • Material handling systems
  • Industrial machinery
  • Automotive industry
  • Military equipment
  • Construction industry

These jacks are ideal for applications where high force and precision are required.

What is the working principle of screw jack?

A screw jack is a simple machine that works on the principle of a screw. It has a long screw shaft that is rotated by a handle or motor. The screw shaft has threads that mesh with a nut. When the screw rotates, the nut moves up or down the shaft, depending on the direction of rotation. As the nut moves, it pushes or pulls the load attached to it.

There are different types of screw jacks, including worm gear screw jacks and ball screw jacks. Ball screw jacks are more efficient and have higher load capacity.

What is the difference between a screw jack and a hydraulic jack?

Screw jacks and hydraulic jacks are both used for lifting heavy loads, but they work differently. A hydraulic jack uses pressurized fluid to lift the load, while a screw jack uses a screw to lift the load. Screw jacks are slower than hydraulic jacks but can handle heavier loads and are more precise.

How to choose or customize the right screw jack?

  • Environment and operating conditions
  • Mounting options
