Hydraulic Cylinders for the Marine Industry
Marine environments are some of the most unforgiving on Earth—where corrosion, constant moisture, saltwater exposure, and fluctuating loads push hydraulic systems to their limits. At Pneu-Hyd Industries, we design and manufacture custom hydraulic cylinders specifically for the extreme conditions of offshore, shipboard, and port-side applications.
Our cylinders are trusted by marine operators, shipbuilders, and equipment OEMs across North America for their proven performance, resistance to corrosion, and long service life. Whether you’re operating in freshwater, saltwater, or brackish environments, our engineering team ensures every cylinder is built to last, perform reliably, and reduce downtime.
We help solve persistent issues like seal failure, pitting, and sluggish actuation due to extreme temperatures or poor-quality materials. With fast lead times, certified quality standards, and full customization, Pneu-Hyd delivers the confidence marine operations demand.
Built for the Demands of Marine Equipment
Precision Hydraulic Solutions for Shipboard and Offshore Systems
Marine equipment is only as reliable as the cylinders driving it. We work directly with ship engineers, marine fabricators, and offshore platform designers to create rugged, purpose-built cylinders that perform in:
- Dockside & Port Equipment – including container lifts, loading ramps, and hydraulic doors
- Onboard Deck Machinery – such as winches, hatch lifters, anchor systems, and davits
- Steering & Rudder Systems – for consistent, powerful response under dynamic sea conditions
- Offshore Platforms & Subsea Applications – where pressure, corrosion, and longevity are critical
We understand marine systems often require space-conscious designs, protected rod ends, and robust coatings to handle both mechanical and environmental stressors. Every cylinder is built to meet exact application specs with full quality control and pressure testing.
