Ball screws

Ball screws serve critical roles in CNC machining and operations. To better assist their functions and ensure adequate maintenance and care, we explain their roles and responsibilities. At its core, a ball screw is a motion conversion mechanism for machinery and equipment across a variety of industrial applications.

A Ball Screw’s Function in CNC Machines

A ball screw is the best assembly mechanism because it is highly accurate. Generally, industrial machinery and heavy equipment will use a ball screw instead of a lead screw because of its precision and attention to detail.

The ball screw is preferred in CNC machining because of its smooth and accurate motion. There is a reduced level of friction among the ball and nut. Most often, the motion will travel along a steel bearing setup, and this creates for a smooth commute within the mechanism.

How Does a Ball Screw Work?

A ball screw is a tool designed to convert rotational motion to linear motion within an application. A ball screw apparatus is made up of a threaded shaft, a nut, and a set of ball bearings that reduce friction between the screw shaft and nut during movement.

Ball Screws in Industrial Applications

Because of their qualities and benefits, ball screws are a good choice for many industrial applications that function using the conversion of rotational motion to linear motion.


Industrial machinery often must operate with extremely high precision or under particularly heavy loads. Ball screws excel in both of these areas, surpassing their lower accuracy and lower load-bearing cousins, the lead screws. Because of their ball bearings, ball screws are able to reduce friction within industrial machines, making operation smoother and extending the machine’s lifespan. This quality is important in industrial settings when a machine will often perform the same task repeatedly in rapid succession. Ball screws are also valued for their ability to perform high-speed movements, and speed has historically been valued within most industrial facilities.

Types of Applications

Ball screws are used in a variety of industrial applications, including:

1) Machine tools

2) General robotics

3) Milling machines

4) Food processing equipment

5) High-precision assembly equipment

6) Industrial robots used in manufacturing

7) Semiconductor manufacturing equipment
