Linear actuators are commonly used in many applications when the requirement is to move or lift an object. They are of many types, and the right one for you rdepends on several factors, such as the job that it is to perform.

When you look at it, all linear actuators do the same job. They help change one form of energy into another, but the type of actuator can impact performance.

Here’s everything you need to know about linear actuators:

What Do Linear Actuators Do?

Linear actuators are used to convert rotational motion into linear motion when external energy source is provided.

If you are looking to make an object move in a specific direction, pull, lift, move or adjust then a linear actuator is what you need to turn to.

It will change rotational energy into linear energy to make it possible for a machine to do its job.

Now many people ask, why can’t we just create linear energy, and why do we need rotational energy first? The answer is simple, because rotational energy is easier to create.

Types Of Linear Actuators

While there are many types of linear actuators available on the market, the most commonly used actuators are of 3 types. These are:

  • Electrical,
  • Pneumatic

Let’s get to know each of them in detail now:

Electrical Actuator

An electrical linear actuator has a simple design as it consists of a motor and a lead screw. When electric current is applied through it, it generates motion in a straight line.

Hydraulic Actuator

These type of actuators have a built-in hydraulic system in them. They require oil to operate and are very quick in performing the job.

However, since they have a complex design, they are difficult to install and operate, and require a professional to do so.

Pneumatic Actuator

Just like hydraulic actuators, these also have a complex system, and are operated on pressure.

When pressure is applied, they convert compressed air into mechanical energy. That’s not all, if your requirement is to produce rotational motion, they can do that too.

How To Keep These Actuators Well Maintained?

The first thing that you need to check is the motion the actuator is providing. Once, it has been used for a year or so, look for signs of motion changes. The actuator may have worn out due to wear and tear and poor maintenance.

In case you find something wrong with the performance of the actuator, make sure you get it checked by a professional.

Poorly maintained actuators do not only work slow but may also cause noise and disturbance.

Where Are Linear Actuators Used?

Their use is extensive. They are used in applications like sliding doors, vehicles, ramps, construction equipment, smartphones and throttle control etc.

Moreover, they are also used in huge machineries that are used in major sectors including the health sector, marine sector, industrial sector etc.
