When your design calls for a linear actuator, you have lots of choices. Pneumatic, electric, rodless, rod, belt driven, screw driven. These are just some of the options available.
If your design calls for a rod-style linear actuator, there are three main types you’ll want to consider:
- pneumatic rod actuators
- traditional electric rod actuators
- integrated or intelligent actuators
Here’s an infographic that may help your selection.
When it comes to easy configuration, pneumatic rod actuators are the winners. They’re simple and straightforward – an industry standard. Electric rod actuators are much more complex since you need to configure the motor, power cord, logic device and more. Integrated linear actuators are just that – integrated. They include the motor and controller so they’re easy to configure, like a pneumatic device.
If power consumption and operating efficiency are issues, consider using a traditional electric rod actuator or an integrated actuator. Pneumatic linear actuators and their supporting pneumatic systems are famous for leaks that drain power, and they only operate at about 10% efficiency. On the other hand, electrical linear actuators operate at 50-70% efficiency, and integrated actuators can typically deliver efficiencies on the upper end of that range. That efficiency means less power consumed to get a job done.
Then there’s flexibility. Pneumatic actuators score low here. They’re dependable workhorses, but not very programmable with respect to positioning or speeds/acceleration. When you need multiple stops and defined speed, electric rod actuators. and integrated actuators are the best choices.
