Imperative Information You Should Know About Linear Actuators

Update on

Since the time when the first linear actuator was produced today’s variants look almost the same. The only thing is that they have been improved in terms of adaptability to different conditions and their versatile sizes. Moreover, the power capability of contemporary actuators is excellent allowing them to work with many sources.

Linear actuators are broadly used in all industries worldwide to provide fast, frequent, and steady movements of the same type whenever it is required for an effective outcome.

At the same time, with the swift developments of other technological innovations, linear actuators of relevant types penetrated the market of connected home devices, especially various examples of electric actuators with their great features.

Many of us use these motion creators every day, but if you ask someone to describe this secret device, then only a handful of people are able to do it. We contact with them at the office, in many shops and even at school. This simple but indispensable technical element is the backbone of many current developments and installations.

What is called a linear actuator?

Describing an actuator in simple terms we get a device that allows objects to move in the necessary direction when it is needed. It means that when implementing this technical innovation in any project, people can manage different items creating the motion in the direct line and returning the object in its opening position.

Furthermore, some actuators can provide rotary and periodical movements. If you compare straight movement actuators and those that have been applied for TV lifts or standing desks, you will see that the last type converts rotational motion into a linear one.

Important information concerning the types of actuators

Automation variety of products is eligible for different projects regardless of their approach and area of activities. Speaking precisely about home smartening up with the help of actuators, we immediately consider the examples of TV lifts, adjustable kitchen worktops, standing desks, hidden storage places, smart windows, etc.

Before choosing the necessary type of actuator, we should understand the features we want to obtain and the conditions the actuator will work in. There are the following actuators that are widespread today:

  • Electrically driven actuators,
  • Mechanical actuators,
  • Liquid-operated models,
  • Air-driven types.

These are major kinds of actuators with their unique aim and power requirements. Whether you have already arrived at the decision and are looking for this little smart mechanism for your home project or still do not know how to choose the one because of a lack of information, read further to discover essential factors.

What factors are important when choosing a linear actuator?

how to choose linear actuator

Though versatile types of actuators are available at the market for industrial and home automation purposes when deciding to select among several models, it is paramount to take out the appropriate actuator for the individual application.

Think about the required conditions before buying the one. Look below to learn important factors concerning the eligible actuator for your project implementation.


In the process of examining the place where your future actuator will be installed, it is essential to point out the kind of motion you need. As these mechanisms are created to make the objects move directly or provide the motion in a circular manner. Evaluating these actions and the way they will work in the whole process is critical.


By choosing an electric actuator you will win a lot, as this type typically fits any application and has been improved for diverse purposes. These actuators are in great demand but they are not usually appropriate for certain conditions. If energy is limited or disabled, it is better to think about the implementation of a pneumatic or liquid-operated actuator.

Force level:

A key function of an actuator is to provide force when operating. Generally, these devices move different objects in the required direction. The work amount performed by an actuator is determined by the desired force necessary to cope with a weight, which is specified by the actuator’s carrying capacity.

Appropriate movement assessment:

Actuators are designed with diverse motors and positioning of the stroke. Do not forget to pay attention to its length which depends actually on the shaft length and motion screw. Before buying an actuator, remember to evaluate at average the number of the required movements your actuator will provide by the ob.


Consider the loading your actuator will need to move, and only after that, you can think about the speed. Using much force in the process of moving weighty objects, an actuator will work not very quickly. You can receive useful information if you calculate the required operating time.

In such a way you will be aware of the necessary speed your actuator should possess to be effective in full scope.

Type of environment:

The level of the actuator’s performance directly depends on the environment of implementation as well. Most of them do not cope with the task properly when working in humid, dirty, or any other ill-fitted conditions.

You can find the types which can work being installed under the water when at the same time, the rest kinds require additional protection cover to deal with the unclean surrounding.

The way of mounting:

Decide carefully before purchasing concerning the eligible mounting. As the more models you will find, the more mounting styles you will discover. For instance, if you plan to have pull or push motions, you should choose the simple stationary mounting. Suitable mounting provides normal operation and good efficiency from the selected actuator.
