No More Backbreaking Lifting: Marine Automation at Your Fingertips
Picture this: The deck is slick. The wind has salt in it. That heavy hatch needs opening. Again. Each time you wrestle with it, your arms and back protest. And there’s always a risk—one wrong move, one slip, and you’re facing more than just a little frustration. Or maybe you’re in a control room, fighting to keep systems moving smoothly, but the “reliable” hydraulic actuator just failed. Fluid’s leaking. Operations stop. Hours get lost.
If you’re nodding along, you’re not alone. Out at sea, even the small chores turn into daily headaches because marine life is tough—on people and on machinery.
Add in the struggle of traditional actuators. Hydraulics and pneumatics need constant care. Seals give up under salt, hoses burst, or air compressors stutter. Maintenance turns into a full-time job. When downtime isn’t just expensive but dangerous, you need a better way.
Let’s face it: you shouldn’t spend so much time pushing, lifting, or fixing. There’s a smarter, safer future—one button at a time.
Meet the Marine Grade Long Stroke Electric Actuator: Your Secret to Seamless Movement
Imagine if all you had to do was push a button, and that hatch lifts itself. No more heavy heaving, no more crawling into tight corners to fix leaks. Just smooth, silent, and precise movement—every time.
That’s exactly what a marine grade long stroke electric actuator does. It’s the “muscle” behind modern marine automation. Inside its sealed shell, the actuator converts electricity into clean, powerful, straight-line (linear) motion. This means it pushes, pulls, lifts, or lowers anything from heavy doors to big valves—even underwater—on command.
So, what makes it “marine grade”? That’s simple: It’s built to survive salty spray, pounding waves, and extreme weather. We’re talking high-grade stainless steel, anodized aluminum, and smart coatings designed to laugh in the face of corrosion. These tough materials ensure years of reliability—even where saltwater eats regular equipment alive.
But there’s more. When you say “long stroke,” you want reach. Our actuators can travel from 300mm up to a jaw-dropping 2000mm (that’s over six feet!). So you can automate even the biggest hatches, the toughest valves, or move antennas and masts with ease.
Why electric? Because nobody wants to mop up hydraulic oil, chase air leaks, or worry if a compressor will fail. Electric actuators are quietly rewriting the rules for marine equipment:
- No messy fluids—just simple wires, plug-and-play.
- Pinpoint precision—move big loads to exactly the right spot, again and again.
- Ultra-low maintenance—sealed design means you can forget constant greasing.
- Energy savings—draws power only when needed, slashing bills and emissions.
You get a taste of real freedom on deck and below, knowing your gear just works.
What Makes a Marine Actuator “Marine Grade”?
Your equipment takes a daily beating. That’s why only certain actuators truly deserve “marine” status. We at Jimi Technology didn’t guess—we engineered for real-world abuse.

1. Armor Against Salt and Water
- Materials: Every actuator uses marine-grade 316L stainless steel or anodized aluminum. So don’t fear rust, even if the unit gets splashed or dunked.
- Saltwater Proof: Special anti-corrosive coatings shrug off salt, so your actuator keeps running for years.
2. Rock-Solid Water Protection
- Look for IP67 and IP68 ratings. These numbers aren’t just for show—they mean you can submerge your actuator (temporarily or even for extended periods), and it keeps working.
- NEMA 4X certifications let you blast the actuator with a hose, or survive monsoons, with zero trouble.
3. Ready for Marine Mayhem
- Each actuator can take on wild temperature swings. Freezing cold or tropical heat, it keeps humming.
- Shock and vibration? We test to marine standards, so even in a storm, nothing shakes loose.
- Sun’s beating down? UV-resistant finishes stop the sun from eating away at exposed parts.
4. Safety and Compliance—No Shortcuts
- Every unit passes checks from big names: ABS, DNV, and Lloyd’s Register. That’s your ticket to worry-free operation (and happy inspectors) on commercial ships or offshore platforms.
Why Long Stroke? When Size (and Reach) Matter
Sometimes standard just won’t cut it. If you need more than a basic push or pull—if you need to automate big tasks—our extended stroke actuators step up. Here’s where they shine:
- Opening/Closing Large Hatches or Doors: Don’t leave crew wrestling with hefty steel. Automate, save time, and keep them safe.
- Controlling Dampers and Vents: In engine rooms or HVAC systems, stroke length means you can vent air or fumes exactly when needed.
- Big Valve Movement: Water, fuel, waste—all controlled at the touch of a button, even when the valve sits far away.
- Deploying Telescoping Masts or Antennas: Get maximum range or best signal without ever leaving the safety of the deck.
- Custom Deck Lifts: Heavy gear on deck? Lift or lower it with precision and ease.
Engineering long-stroke movement isn’t only about distance—it’s also about smoothness and reliability. That’s why we add rod guides, beefier bearings, and smart feedback systems. So the actuator moves evenly, quietly, and with repeatable force from start to finish.
Electric vs. Hydraulic vs. Pneumatic: Let’s Settle the Debate
Old-school hydraulic and pneumatic systems once ruled marine machinery. But they struggle with leaks, breakdowns, and plenty of headaches. Now electric power leads the way:
1. Total Control
- Position Feedback: With integrated encoders or servo technology, you hit the same position every time, accurate to fractions of a millimeter.
- Variable Speed: Adjust speed as needed—quick for setups, slow for heavy or critical loads.
- Consistency: Every cycle looks like the last, with no fluid resistance or air pressure hiccups.
2. Energy Champs
- Electric actuators only “drink” power when they move—not all the time like pumps or compressors.
- That means you use up to 60-70% less energy. Good for your budget, good for the planet.
3. Maintenance? Nearly None
- No oil, no filters, no pipes. Actuators arrive sealed, self-lubricated, and need hardly any attention.
- In our experience, electric systems slash downtime by up to 95% compared to fluid-driven ones.
4. Easy Install, Easy Integration
- Just run wiring and attach a mounting bracket—forget about plumbing.
- They plug right into vessel control systems using PLC, CAN bus, or Modbus interfaces.
- Pair with a controller for even smarter performance.
5. Safe and Clean
- Zero risk of oil spills or hazardous leaks.
- Silent running keeps the ocean peaceful, and your crew less stressed.
What to Look For: Key Specs to Nail Your Selection
Choosing the right marine grade long stroke electric actuator isn’t about picking the fanciest name. It’s about getting specs that match your task—no more, no less.
Performance Metrics

- Force/Thrust: Do you need to move 100kg, 1000kg, or more? Check the actuator’s rating (in kN or lbs).
- Speed: Measured in mm/s or in/s; some applications need quick moves, others need slow, steady force.
- Stroke Length: From 300mm up to over 2000mm—choose the travel you need.
- Duty Cycle: Will it operate constantly or only sometimes? Pick one designed for your usage.
Electrical Details
- Voltage: 12V/24V DC for small/medium duties; 110V/220V AC for serious lifting.
- Current Draw: This impacts your wiring and power supply choices.
Smart Features
- Built-in position feedback sensors (Hall effect, potentiometer, or encoder) for perfect stops.
- Integrated limit switches to avoid overtravel.
- Overload protection so you never jam or burn out.
Mechanical Toughness
- Plenty of mounting options for easy retrofit on any vessel.
- Rod ends that fit your linkage or bracket style.
- Compact housings so you can install them even in tight spots.
