36 Inch Stroke Linear Actuator 12V Heavy Duty 440lbs - Waterproof

In this review of the 36 inch stroke linear actuator, the bottom line is straightforward: this is a heavy duty, 12V electric actuator built for lifting and pushing applications where a long stroke and solid holding force matter most. It suits hobbyists and professionals who need a reliable 900mm stroke with a self-locking motor and IP65 protection for occasional outdoor use. The single biggest reason to buy is the combination of a 36 in stroke and a rated 440 lb push capacity, which lets it handle sizable loads that shorter actuators cannot.

Key Features

• 36 in Stroke: Provides 900mm of travel for long-reach adjustments and large lift ranges without complex linkages.
• 440 lb Push Capacity: Delivers up to 2000N of pushing force so it can move heavy panels and structures with confidence.
• Self-locking Motor: Holds position when power is removed, preventing drift in raised or extended positions.
• Built-in Limit Switches: Automatically stops at fully retracted and fully extended positions to protect the mechanism and motor.
• IP65 Waterproofing: Weather-resistant housing makes the unit suitable for outdoor and indoor installations where dust and light water exposure occur.
• Quiet Operation: Plastic geartrain and aluminum body keep noise under about 50dB for less disruptive operation.

Who It's For

This actuator is well suited to DIYers, fabricators and small manufacturers who need a long-stroke linear drive for applications such as electric beds, solar trackers, adjustable booths, or lift frames. The combination of a 36 in stroke and 440 lb pushing force makes it a good fit where medium to heavy loads must be moved over a long distance.

It is not the best choice for high-speed applications or continuous duty motors that require rapid actuation, since the no-load speed is about 0.31 in/sec and the motor draws up to 5A under load. Buyers who need very high cycle rates or integrated control electronics should consider a different actuator system.

Pros & Cons

Pros

• Long 36 in stroke that covers large travel requirements without extra linkages or telescoping hardware.
• Strong 440 lb push rating and 330 lb pull capability for demanding lifting tasks.
• IP65-rated build and self-locking motor for secure positioning in outdoor or dusty environments.
• Quiet, stable operation thanks to plastic gears and an aluminum alloy body.

Cons

• Relatively slow speed at about 0.31 in/sec, which may be noticeable in time-sensitive applications.
• Designed for intermittent duty; not specified for continuous heavy cycling.

Specifications

Our Verdict

The 36 in 12V actuator is a practical, value-oriented choice for projects that need lengthy travel and solid holding power without complex installation. Its waterproof casing, built-in limit switches and self-locking motor make it reliable for intermittent lifting tasks, and the included mounting brackets simplify installation. Choose this unit when strength and stroke length matter more than actuation speed.

Frequently Asked Questions

Can this actuator be used outdoors?
Yes, the IP65 rating makes it suitable for outdoor use where it may encounter dust and light water exposure, but avoid full immersion.

What is the push and pull capacity?
The actuator provides up to 440 lbs (2000N) push and about 330 lbs pull capacity according to the product specification.

Does it stop automatically at the ends of travel?
Yes, built-in limit switches cause the actuator to stop at fully retracted and fully extended positions.
