A Step-by-Step Guide to Selecting the Right Linear Actuator

Process for Specifying Your Linear Actuator

Customers sometimes tell me they feel overwhelmed when choosing an actuator. There are so many variables, load, speed, stroke, environment, controls and each one affects the rest. But once you break it down, the process becomes clearer.

1. Define the Load.
Not just the weight, but the dynamic forces. Shock, start-up loads, angles, friction, they all matter.

2. Decide the Stroke Length.
It sounds simple, but this often becomes the defining constraint for mounting and speed.

3. Determine the Speed.
Faster is rarely better. It’s about what the application needs.

4. Consider Duty Cycle.
How long will it run? How frequently? This is where many failures begin.

5. Check the Environment.
Dust, washdown, outdoor exposure, IP ratings protect your investment.

6. Think About Control.
Do you need simple in/out control, or more precise synchronisation?

7. Confirm Mounting Options.
The mechanical setup shapes everything else, often more than people expect.

Every project benefits from slowing down at the beginning and checking each point carefully. It saves far more time than it costs.
