Adjustable Stroke Linear Actuators
Adjustable Stroke Linear Actuators
Description
The Adjustable Stroke Series is a world-first innovation by FIRGELLI®, offering the ultimate flexibility in linear motion control. Unlike standard actuators with fixed stroke lengths, this premium unit features an Externally Adjustable Limit Switch mechanism. By simply sliding the adjustment device on the body, you can fine-tune the end-of-stroke stopping position by up to 1 inch (25.4mm). This allows for perfect installation fitment without the need for custom fabrication or complex control systems.
Built for reliability, the series is manufactured from Aerospace-Grade Aluminum and sealed to an IP66 rating, ensuring protection against dust and powerful water jets. With built-in limit switches to prevent over-travel and zero-maintenance architecture, this actuator is the definitive choice for engineers who demand adaptability and longevity.
Key Features
- Stroke Adjustability: Instantly shorten the extended stroke by up to 1" for precise alignment.
- Premium Build: High-grade aluminum housing offers superior strength and corrosion resistance.
- IP66 Protection: Dust-tight and water-resistant for harsh indoor or outdoor environments.
- Versatile Power: Available in 35 lb, 150 lb, and 240 lb force options to match your load requirements.
- Maintenance-Free: Sealed design requires no lubrication or servicing over its lifespan.
Compatible Accessories (Sold Separately): MB1-P Brackets - MB6-P Body Brackets - MB10 Rod End Brackets - MB-PB Base Bracket (Column Lift Conversion) - Remote Systems
