Choosing the right linear actuator isn’t just about force or stroke — it’s about matching the whole system to your application.
Most actuator selection advice only scratches the surface. But real-world projects fail or underperform when important factors — like duty cycle, mounting geometry, control strategy, or load type — are overlooked.
To help designers, builders, engineers, and DIYers get it right the first time, we created a comprehensive engineering reference guide that consolidates decades of experience into one definitive resource.

Why This Guide Is Different
✅ Engineering-first, not marketing-first
This guide is written to be referenced again and again — like a handbook.
✅ Focused on real-world failure prevention
Most early actuator failures are not product defects — they’re design and integration errors. This guide shows you how to prevent them.
✅ Actionable models and checklists
Beyond theory, it includes practical sizing models, mounting rules, control strategies, and a final checklist you can use on your next build.
Who the Guide Helps
This resource is ideal for:
-
Mechanical designers and engineers
-
Automation and robotics builders
-
Makers and DIYers scaling up projects
-
Product developers specifying actuators
-
Anyone who wants their actuator system to last
Even if you’ve used actuators before, you’ll likely find a concept or detail you missed — especially around geometry, duty cycle, or control.
How to Use This Guide
-
Start with your application
— What motion, force, and environment do you need? -
Use the selection criteria
— Balancing force, speed, and duty cycle early reduces redesign later. -
Check mounting & geometry
— Side loads and misalignment are the most common causes of failure. -
Review sizing models
— Don’t rely on weight alone — use real force models. -
Choose control strategy last
— Feedback and synchronization matter for multi-actuator systems.
For each step, the guide links to visuals, formulas, and real-world examples you can rely on.
Final Thought
Whether you’re building an automated hatch, an adjustable desk, a robot arm, or an industrial positioning system, actuator selection is a systems problem — not a single-number problem.
Save time. Reduce failures. Build with confidence.
