Pneumatic Actuator

 

Traditionally, pneumatic actuators provide higher speeds and lower forces when compared to electric actuators. However, a few factors, such as screw pitch/lead from an electric actuator, or the number of pistons in the pneumatic actuator, can affect the comparison.

For a pneumatic actuator, the force is calculated by multiplying the piston area (force factor) by the air pressure in the cylinder. For an electric actuator, the linear force is converted from the motor's torque.

It's difficult to maintain a set speed or force consistently when you're dealing with compressed air. Since voltage and current are easier to control, electric actuators can maintain force and speed much better even without closed-loop feedback. Ball screws or rack and pinion mechanisms on electric actuators also act as a gear reduction ratio, so forces can be increased with sacrifice to speed.

There are many options for electric actuators, so make sure you're comparing apples to apples. Even switching out a ball screw with another ball screw with a higher pitch/lead will alter the final specifications as you can see in the chart below.

 

The following chart depicts an example of force vs speed for linear actuators.
