PA9 Industrial & Solar Linear Actuator — 40000N Thrust, Extreme Power for Industry and Solar Farms, Direct from the Source Factory
Introducing the PA9 Linear Actuator
Sitting between our PA8 and flagship PA10, the PA9 linear actuators deliver a massive maximum load of 40000N (4 tons) of thrust — an ideal balance of extreme power and exceptional value. Engineered for the toughest industrial duties and large-scale solar installations, the PA9 series ships directly from our own factory, with no middlemen and no inflated markups.You can go to watch example videos on YouTube. It can help you to understand how is solar tracker working, and how is the linear actuators applying to soar tracker. Otherwise you can go to my YouTube channel to study all the constructions of single axis solar trackers and dual axis solar trackers. If you have any questions, you can contact us on website.
40kN of Heavy-Duty Power
The PA9 is a true powerhouse among heavy duty linear actuators. With 4 tons of thrust on demand, it confidently replaces hydraulic systems in applications such as:
- Heavy industrial lifting platforms and press equipment
- Large agricultural, mining, and construction machinery
- Marine deck machinery, hatch covers, and winch systems
- Heavy-duty material handling and compaction equipment
- Large industrial gates, dampers, and ventilation control
- Utility-scale solar power plants
As a fully electric solution, the PA9 heavy duty linear actuators eliminate hydraulic pumps, oil leaks, and warm-up delays — delivering hydraulic-class force with clean, precise, low-maintenance electric control.
Engineered for Solar Tracker Systems
The PA9 excels as a linear actuator for solar tracker system applications at utility scale. When a single tracker row carries hundreds of PV panels, pivoting them against gravity and wind loads demands serious muscle — plus decades of outdoor endurance. Our solar-optimized PA9 delivers:
- Massive 40kN thrust for large single-axis and dual-axis tracker arrays
- High IP66-rated sealing against dust, rain, sandstorms, and snow
- Corrosion-resistant construction for desert, coastal, and tropical environments
- High duty cycle design for continuous daily sun tracking over decades of plant operation
- Low standby power consumption for battery-backed and off-grid installations
- Precision feedback options (hall sensors, encoders) for accurate multi-row synchronization
Flexible Power Configurations
The PA9 is available in 24V, 48V DC and industrial AC voltage options — perfectly matching solar plants with 24V/48V battery systems as well as heavy industrial power setups. Built-in limit switches, thermal overload protection, and optional manual override ensure safe, dependable operation in every condition.
Why Buy Direct From the Source Factory?
As the direct source manufacturer, we control every stage of production — from motor winding and precision gear machining to assembly and full-load testing. Buying direct from the factory means:
- Factory-direct pricing — outstanding cost performance in the 40000N heavy-duty class, critical for large solar EPC project budgets
- Guaranteed genuine components — no refurbished or substandard parts, ever
- Fast lead times — bulk and container orders shipped on project schedules
- Full customization — stroke length, speed, voltage, protection rating, mounting brackets, and feedback systems tailored to your design
- Professional engineering support — direct from the team that designs and builds the product
Every PA9 actuator is 100% factory tested for full load, stroke, speed, sealing, and endurance before shipment. OEM and ODM partnerships are warmly welcomed — we proudly support solar EPC contractors, tracker manufacturers, and industrial equipment builders worldwide.
