How Linear Actuators Work in Power Windows

How Linear Actuators Work

Manually opening and closing windows can be very inconvenient, especially those in hard-to-reach places. Electric window openers were developed to solve this problem. By having power windows installed, you’ll probably enhance your property’s energy performance as well. Those who consider remote-operated windows might wonder how an electric window opener operates. If that is the case, keep reading because this article will explain how linear actuators work.         

How Do Linear Actuators Work?

Linear actuators undergo several processes that enable them to provide push and pull movements. With the help of these devices, opening or closing windows becomes possible with a simple button press. Nevertheless, the usefulness of linear equators is not limited to power windows. You can also witness these devices performing other tasks for kitchen appliances, desks, televisions, and more.

These window components require two inputs – energy source and external signal. The two inputs work together to create rotary and linear motion. Because electric window openers generate substantial amounts of force, they make great additions to domes and roof lights. Let’s explore the two primary opening mechanisms utilized by power windows below.

How Linear Actuators Work



As the name implies, an extendable pole lies on the track. Both the rod and track reside in an external housing for protection. As the extendable pole receives electric power from the motor, it expands. This particular mechanism is the one in charge whenever you need to open your window.

Rack and Pinion

So, how do these two elements cooperate in opening windows? The circular gear called the pinion first engages the teethed rack. Not long after that, power is applied to the mechanism, making both the rack and pinion move. Most power windows have their racks housed in external casings.

Do you know that one of the most common uses of linear actuators is window automation? Yes, they’re known as the push-rod motor, and they have been used to control windows. You can use a large linear actuator in various window automation include:

  • Shutters
  • Skylights
  • Casement windows
  • Top or bottom hung windows 

There are various types of electric window openers, or automatic window openers are available in the market. Here are few common types: 

Single Chain Window Openers

These types of window openers are best suited for skylights, top hung, bottom hung, and standard casement windows.

Twin Chain Window Openers 

Twin Chain electric window openers are suitable for large windows such as smoke control and large, heavy windows.

Linear Actuators For Roof Vents & Dome Windows

If you’re looking for a linear actuator for your dome windows, go with Max actuators. They’re specifically designed for heavy roof vents and domes. 

Panels and Switches

They are perfect for Smoke control panels, AOV smoke ventilation, and automatic opening vents.

The Benefits of Utilizing Electric Window Openers

How Linear Actuators Work


Here are some of the numerous benefits of installing linear actuators for your windows:

Improved Airflow 

With the window openers, you’ll always get fresh air, and there will be good airflow. Whether it is your office windows or house ones, it will keep the space well ventilated. They come with a wide variety of complementary systems such as rain sensors and failsafe battery backups. Additionally, there is a timer, so you can set it to open and shut the windows when you aren’t there.

Minimal Health Risks 

Some window-opening methods produce by-products that are harmful to us and the environment. Fortunately, an electric window opener doesn’t require hazardous energy sources such as fossil fuel to function. This perk makes them suitable for individuals who strive to minimize health risks.


The natural ventilation provided by power windows might eliminate the need for air conditioning. Although many property owners rely on air conditioners to dissipate heat, this option is not very cost-efficient. Opting for electric-operated windows instead would likely come with cheaper long-term expenses.

Perfect for Hard-To-Reach Places

Opening and closing elevated windows were almost impossible without equipment back then. Following several technological innovations, the invention of linear actuators made things much easier for homeowners. Installing linear actuators is especially helpful for the disabled and the elderly since they usually have restricted movement.


Each automated window option comes with a different set of pros and cons. Taking your needs and goals into consideration would help you come up with the right decision. For those who find the benefits mentioned above appealing, having linear actuators installed might be ideal for you. Select the one according to your requirements. Lastly, you should also ensure that you’re working with a reputable company to obtain satisfactory results.
