High Force Linear Actuator PA-17 20in Stroke - 850 lb Push/Pull

Our review of the PA-17 high force linear actuator finds it best suited for industrial users and DIY engineers who need a compact, heavy duty 12V actuator for lifting, pushing or pulling large loads. The single biggest reason to consider this unit is its combination of robust mechanical design and IP65 protection: a stainless steel shaft with metal gears rated to push or pull up to 850 lb and hold up to 1700 lb, which makes it a practical choice where strength and weather resistance matter.

Key Features

• High force: The actuator delivers up to 850 lb push/pull force and can hold up to 1700 lb, letting it handle demanding lifting and pushing tasks.
• Durable construction: A stainless steel shaft with metal gears improves wear resistance and longevity in heavy use applications.
• IP65 protection: Sealing against dust and water spray provides reliable operation in harsh outdoor and ag environments.
• Overload safety: A mechanical slip clutch offers protection from stalls and overloads to reduce risk of damage.
• Simple integration: A 2-wire brushed DC motor and Molex Mini-Fit Jr 2-pin compatible connector make wiring and controller compatibility straightforward.
• Adjustable limits: Built-in adjustable limit switches are included for stroke lengths up to 24 in so travel can be set precisely.

Who It's For

This actuator is aimed at industrial operators, farmers, fabricators and hobbyists building heavy equipment who need a 12V linear actuator with substantial force and weather protection. Typical uses include agricultural machines, gate openers, RV sewage gates, solar trackers, small lifts and custom machinery where sustained load holding and rugged construction matter.

Those who should look elsewhere include users needing silent, ultra-smooth motion for high-precision lab equipment or medical devices that require brushless motors, and buyers who require integrated controllers, sensors or strokes beyond 24 in without confirming limit switch compatibility.

Pros & Cons

Pros

• Strong mechanical design provides reliable push/pull force and high load holding capacity.
• IP65 rating and stainless shaft make it suitable for outdoor and agricultural environments.
• Easy 2-wire operation and common connector simplify installation and controller pairing.
• Adjustable limit switches and mechanical slip clutch add useful protection and setup control.

Cons

• Uses a brushed DC motor, so it is not as quiet or long-lived as brushless options in some precision applications.
• Stroke options are limited to lengths with built-in limit switch support up to 24 in, so very long travel needs separate consideration.
