How to Select the Right Linear Actuator
Choosing the right AC-powered linear actuator depends on the requirements of your application. Consider the following factors when evaluating your options.
Capacity & Travel
Determine how much force and movement your application requires.
- Capacity: force required to move and hold the load
- Travel: required distance or range of motion
Voltage & Speed
Match the actuator to your power supply and required operating speed.
- Voltage
- Required movement speed
Duty Cycle & Orientation
Consider how the actuator will operate within your system.
- Duty cycle: percentage of time the actuator is in motion
- Orientation: direction in which the actuator’s force is applied
Operating Environment
- Operating conditions
- Outdoor-use requirements
- Food-grade material requirements
