What are the 4 types of linear actuators?

Linear actuators are devices that convert rotary motion into linear motion, and there are several types available on the market. Here are four common types of linear actuators:

1. Electric linear actuators: Electric linear actuators are powered by an electric motor and are commonly used in industrial and automation applications. They can be controlled with precision, have a long lifespan, and are often easy to install.

2. Hydraulic linear actuators: Hydraulic linear actuators are powered by pressurized fluid, typically oil. They can generate high forces and are commonly used in heavy-duty applications such as construction equipment and material handling.

3. Pneumatic linear actuators: Pneumatic linear actuators are powered by compressed air and are commonly used in manufacturing and industrial applications. They are generally lightweight, durable, and can be operated quickly.

4. Mechanical linear actuators: Mechanical linear actuators use a screw, belt, or other mechanism to convert rotary motion into linear motion. They are typically less expensive than other types of linear actuators, but are also less precise and have a shorter lifespan.

Each type of linear actuator has its own unique advantages and disadvantages, and the choice of which type to use depends on the specific application and requirements of the project.
