Technical Information
Brand, model, capacity and technical documents will be published after company verification.
Hydraulic cylinders convert pressurised oil into linear motion. On ships they are used extensively in hatch covers, ramps, crane booms and steering gear.
The marine environment wears rod surfaces and seals quickly. Choosing the right coating and seal material directly determines cylinder life.
