Why Space Constraints Kill Your Design (And How to Fix It)
Engineers in robotics, medical devices, and automation face the same frustration: traditional actuators are too bulky for modern compact designs. Here’s what’s holding you back:
✗ Bulky Actuators Waste Space
Standard linear actuators occupy 30-50% more space than needed, forcing design compromises.
✗ Poor Precision = Failed Prototypes
Low-end micro actuators lack the ±0.02mm repeatability required for medical or lab equipment.
✗ High Costs for Custom Solutions
Custom machining for compact motion systems can inflate costs by 40-60%.
✗ Slow Lead Times
Waiting 8-12 weeks for specialized parts delays your entire project timeline.
YIDI Motion’s miniature electric linear actuators solve all four problems—see how.

Frequently Asked Questions
What’s the smallest stroke length available for your miniature electric linear actuator?
Our standard models start at 2mm stroke, but we can customize down to 1mm for micro-precision applications like lab equipment or semiconductor handling.
Can you provide CAD models for integration into our design?
Yes! We provide STEP, IGES, and SolidWorks files for all standard models. For custom designs, CAD files are included with your quote within 24 hours.
How does your pricing compare to Firgelli or Actuonix?
Our factory-direct pricing is typically 20-30% lower than Firgelli or Actuonix for comparable specs, thanks to our China supply chain and automated production. Request a quote to see the difference.
What’s your lead time for custom miniature actuators?
Standard models: 7-14 days. Custom designs: 21-30 days (including prototyping). Expedited shipping is available for urgent orders.
Do you offer PWM or analog control options?
Yes! Our actuators support PWM (0-100% duty cycle), 0-5V analog, and digital control (via UART or I2C). We can also integrate Hall sensors or encoders for closed-loop feedback.
Are your actuators suitable for medical or food-grade applications?
Absolutely. We offer FDA-compliant materials (e.g., stainless steel, food-grade lubricants) and IP67-rated models for medical devices, lab equipment, and food processing.
What’s your warranty policy?
All YIDI Motion actuators come with a 2-year warranty. For custom designs, we offer a 30-day performance guarantee—if it doesn’t meet specs, we’ll replace or refund it.
