Marine Hydraulic Cylinder
JW HYDRAULICS designs and manufactures high-performance marine hydraulic cylinders tailored to withstand extreme saltwater corrosion, heavy loads, and demanding offshore operations. Built with corrosion-resistant materials (e.g., stainless steel, nickel-plated coatings) and advanced sealing systems, our cylinders ensure leak-free functionality in submerged or splash zones, even under high-pressure conditions.
Key Features of Marine Hydraulic Cylinder
Robust Durability: Reinforced structures and anti-abrasion surfaces for long-term reliability in tidal, wave, and subsea applications.
Saltwater Resistance: Multi-layer protection against pitting, rust, and biofouling, compliant with DNV-GL, ABS, and ISO 15540 standards.
Custom Solutions: Configurable bore sizes (50–500+ mm), stroke lengths, and mounting styles for ship steering systems, cranes, winches, hatch covers, and offshore platform equipment.
Low Maintenance: Self-lubricating components and fail-safe designs minimize downtime in remote maritime settings.



JW Hydraulics supplies marine hydraulic cylinders for meeting the demanding conditions of maritime applications. Our cylinders are engineered for exceptional durability, corrosion resistance, and high load-bearing capacity, making them ideal for use in ship steering systems, deck machinery, offshore platforms, and other marine equipment.
