When your actuator stops working, it doesn’t necessarily mean you need to replace the entire system. In most cases, you can simply find a compatible replacement actuator that matches your old one — restoring full functionality without redesigning your setup.
A failed actuator can halt an entire system, but replacing it with a compatible model is often faster, easier, and much more affordable than redesigning or rebuilding your equipment from scratch.
At Progressive Automations, we make this process simple with our Actuator Replacement Chart. You can quickly search by your actuator’s model number or manufacturer to find an equivalent unit from our catalog.
Identify the Type of Actuator
Start by confirming what type of actuator you currently have. The three main categories are electric, pneumatic, and hydraulic. Electric actuators are the most common and easiest to identify. They include a small motor housing and electrical wires or connectors. Pneumatic or hydraulic actuators use pressurized air or liquid to create motion. These can often be replaced with electric models that match their stroke and load capacity. Switching to an electric actuator can simplify maintenance, improve control, and increase efficiency — especially in modern automation systems.
Determine the Key Specifications
Once you’ve identified the type, gather the main specifications of your actuator. You can usually find these on its label or in the product manual.
Force Rating (Load Capacity) – Check how much force the actuator can push or pull. The rating is typically shown in pounds (lbs) or newtons (N). Choose a replacement actuator with equal or slightly higher capacity for safety and durability.
Stroke Length – Measure the distance your actuator travels between the fully extended and fully retracted positions. This defines the stroke length — one of the most important parameters to match.
Mounting Distance (Hole-to-Hole) – Also known as the installation distance, this is the measurement between the two mounting points of your actuator (from the motor end to the rod end). Matching this ensures your new actuator fits perfectly into the same mounting setup.
Power Supply – Determine whether your actuator runs on AC or DC power. Common ratings include 12VDC, 24VDC, and 48VDC for DC models, or 110VAC/220VAC for AC units. Always match the voltage and polarity of your existing power source.
IP Rating (Environmental Protection) – The IP rating indicates how well your actuator is protected from dust and moisture. For indoor or controlled environments, IP20 to IP54 is sufficient. For outdoor or harsh conditions, choose IP65 or higher for maximum protection.
Speed and Noise Level – These specs are often found in datasheets. If unavailable, you can estimate them during operation. For non-critical applications, an approximate match is usually fine.
Check for a Feedback Sensor
Some actuators include internal feedback systems, such as potentiometers or Hall effect sensors, which provide position information. You can easily tell if your actuator has one by checking the number of wires:
- 2 wires → no feedback
- 3 or more wires → feedback sensor built in
If your system uses feedback for control or synchronization, choose a replacement actuator with the same feedback type.
How to Use Our Actuator Replacement Chart
Once you have your specifications, it’s time to find the perfect match using our Replacement Chart. The tool makes it easy to locate a Progressive Automations model that fits your application.
Here’s how it works:
Search by Model – Enter your actuator’s existing model number (for example, LA31 or CAHB 22) and click “Check Compatibility.” The system will automatically show the most compatible Progressive Automations models with similar specs.
Search by Brand – If you don’t know the exact model number, select your actuator’s manufacturer from the list (e.g., Linak, TiMotion, Ewellix, Thomson, Firgelli, or Other). Then choose the closest model from the dropdown and click “Check Compatibility.”
Review the Results – You’ll instantly see one or more Progressive Automations linear actuators that match your model. Always double-check the datasheet to confirm key specifications like stroke, load, and mounting dimensions.
This simple tool helps you find your replacement actuator in just a few clicks — no need to compare specs manually or contact multiple suppliers.

- Choose a slightly higher force rating for extra safety.
- Confirm your voltage and connector type before installation.
- Keep your old actuator’s label information — it helps future replacements go faster.
Finding the right replacement actuator doesn’t have to be complicated. With a few simple measurements and our Replacement Chart tool, you can locate the perfect match in minutes and keep your automation system running smoothly.
FAQ about Replacement Chart Tool
How do I find the right replacement for my actuator?
Use our Replacement Chart to compare your actuator’s model number or manufacturer and find compatible Progressive Automations units.
Can I replace a pneumatic or hydraulic actuator with an electric one?
Yes. Electric actuators can replace pneumatic or hydraulic systems in most cases, as long as load, stroke, and mounting dimensions match.
Do I need to modify wiring for a new actuator?
Usually not. Most replacements operate on the same voltage, but always confirm connector type and polarity.
What if my actuator’s model number isn’t listed?
Select “Other” in the Replacement Chart and enter as much information as possible — our team can help find the closest match.
Where can I find product specifications?
Every Progressive Automations actuator includes a downloadable datasheet with detailed specs, dimensions, and wiring information.
