Five Things to Consider When Choosing a Linear Actuator

In fact, time runs very fast, and sometimes we do not have enough time to relax or do something for pleasure. That is why people throughout the world try to create and develop new modern technologies to automate our life and make them easier. Actually, all of us can have some ideas for new technologies or robots, which will be useful in our daily life.

You may have heard a lot about different robots, automated doors, lifts, windows, etc. In most cases, when we need to produce a linear motion, we use various linear actuators. However, there are many types of them, which can be used for different technologies and machines. So, in this article, we are going to look for five things to consider when choosing a linear actuator.

Of course, while selecting a linear actuator, you may face various hardships regarding its shape, size, type, and operational principles. But still, first of all, you should select the drive mechanism for your application. Nowadays, there are two of the most widespread drive options. They are a ball screw and a toothed belt. However, in accordance with the Internet website, there is a list of things to consider when choosing a linear actuator. You can order replacement parts like qd114a starter from online sites as well.

The length of the stroke

 The main thing while choosing a linear actuator is the length of the stroke. It is the distance, which the actuator should move in one direction. As for the ball screw actuators, they are usually at the length of 1000 mm or even less. If the ball screw gets longer, it can start to whip like a jump rope.

As for the toothed belt actuators, the capability to tension the belt limits the max length. In other words, the length can be 10-12 meters.

Speed

The next important thing while choosing a linear actuator is speed. As for the ball screw actuators, they usually reach a speed of 5 m/s. However, speaking about the toothed belt actuators, their maximum speed can reach 1.5 m/s.

Accuracy

In general, accuracy is a rather important feature while choosing a linear actuator. It is widely used to mean travel accuracy, positioning accuracy, and repeatability. As for the ball screw actuators, they are mostly preloaded. Their positioning accuracy is better than of the toothed belt actuators.

Mounting

 Speaking about the mounting, in most cases the direction plays a great role in choosing the better drive mechanism. Both variants suit well for inclined and horizontal mounting operations. However, applications with vertical mounting require more careful evaluation.

Maintenance

 The lack of lubrication can induce the failure of linear actuators. Actually, both belt drive and ball screw actuators need the guide system to be lubricated periodically. But still, ball screw actuators need to monitor another component for better lubrication. And as for the belt drive actuators, they need to maintain fewer components.

   So, now you know at least five things to consider when choosing a linear actuator. Both belt drive and ball screw actuators have some benefits and characteristics. You should remember that belt drive actuators are for high speeds and long strokes. And as for the ball screw actuators, they are for applications, which need vertical mounting or high repeatability.
