Product Details

Corrosion-Resistant Through-Rod Hydraulic Cylinder for Marine and Port Equipment

APEX CDRC Series | Marine-Grade Protection | Double-Acting

Engineered for global marine, port, and offshore applications, this through-rod hydraulic cylinder features corrosion-resistant piston rods, marine-grade coatings, and moisture-resistant seals to withstand saltwater exposure, high humidity, and continuous vibration. It provides equal force and speed in both directions, making it ideal for synchronized lifting and positioning in hatch covers, RoRo ramps, and offshore cranes.

Marine corrosion resistance: Hard-chrome or specially treated rods, stainless-steel options, and marine-grade coatings resist saltwater and humidity.
Equal bidirectional motion: Balanced-area design delivers equal force and speed, critical for synchronized multi-cylinder operations.
Load-holding safety: Optional pilot-operated check valves or counterbalance valves for secure holding under external loads.
Position feedback: Sensors available for stroke monitoring and automated control.
Customizable seals and structure: Application-specific seals for extended temperature ranges and vibration resistance.
