BELT DRIVES vs BALL SCREW ACTUATORS | Which one is the best choice for your application?

In this video, we are discussing Belt Drive vs Ball Screw Actuators, and which one is the best choice for your application?

An actuator is a device that uses an electric motor rotation into a linear movement.

Today, linear actuators play a significant role in a broad range of advanced automation applications. From the simple movement of raw material in a manufacturing environment to advanced robotic systems for the precise positioning of a machine tool, linear actuators provide fast, efficient, and repeatable motion for a variety of tasks.

Here at John Brooks, the two of the most widely used types of linear actuators we supply are belt- and ball screw driven actuators. Explore our range by following this link https://johnbrooks.co.nz/products/ele...

A belt-driven actuator converts rotary motion to linear motion by means of a timing belt connected between two pulleys at either end of the drive. The timing belt is typically constructed of a steel-reinforced polyurethane belt for demanding high linear speed applications

The belt drive is enclosed within an aluminium body with the load-carrying carriage riding on top along rails. In contrast to a ball-screw actuator, the driveshaft is oriented at right angles to the side of the actuator.


In ball screw driven actuators, the rotation of the ball screw drives the ball nut and mounted carriage to achieve the desired linear motion. The screw has a precision ground or rolled helical groove to drive the nut along for high load accelerated applications, but is limited in stroke length, in contrast, the driving motor is mounted inline with the actuator stroke.

At John Brooks, we believe that both belt drives and ball screw drives have performance benefits. Belt-driven actuators remain the better choice for applications with lower loads, especially where higher speed and longer stroke lengths are needed. Ball screw driven actuators are the better choice in applications where high loading and/or thrust forces are required, along with highly accurate positioning.
