Marine & Offshore Hydraulic Cylinder – Corrosion-Resistant Custom Series
Engineered for the demanding marine, port, and offshore environment, our cylinders provide reliable hydraulic actuation for critical deck machinery and cargo handling equipment, with robust corrosion protection.
Key Selling Points
- Saltwater Corrosion Resistance: Marine-grade coating and optional stainless-steel components withstand harsh salt spray.
- Reliable Load Holding: Optional counterbalance and pilot-operated check valves ensure safe load control in lifting applications.
- Synchronized Multi-Cylinder Operation: Designed for applications requiring coordinated movement, such as ramps and hatch covers.
- Vibration & Motion Resistance: Built to operate reliably under continuous vessel motion and impact loads.
- Low Leakage Sealing: Moisture-resistant seals minimize external leakage in demanding conditions.
- Position Feedback Options: Linear transducers or proximity sensors available for precise control.
