Marine Hydraulic Cylinders

Engineered for Demanding Offshore and Subsea Environments

Our HOL/WM series welded marine hydraulic cylinders, manufactured here in the UK, are designed and built to meet the stringent requirements of ISO 6020/2 – 1991 and DIN 24554 standards. With heavy-duty construction, a wide range of mounting styles, and fully customisable design features, these cylinders are ideally suited for the harsh conditions of marine and subsea applications.

We can also supply custom design hydraulic cylinders tailored to your specific application and operating parameters – just complete our Hydraulic Cylinder Design Form with as much detail as you can, and we’ll then be in touch to confirm your requirements in full.

Heavy-duty construction – robust design for marine and subsea environments.
Customisable mounting styles – adaptable to a wide range of installations.
3D design integration – cylinder and actuator models can be exported directly into your machine design.
Precision manufacturing – CNC-machined components ensure interchangeability and responsive lead times.
Generous internal bearing lengths – for durability and long service life.
Proven sealing systems – choice of seal types and materials to suit application demands.
End-of-stroke cushioning – available at either or both ends for smooth operation.

Our marine hydraulic cylinders can be supplied with:

Internal full displacement positional transducers
End-of-stroke sensors
Control valve packages – valves built directly into the cylinder endcap or manifolded onto the cylinder

All subsea and marine cylinders are tested to 1.5x the designed working pressure. Standard finish is satin black enamel paint, but cylinders can also be supplied with plated, shotblasted, or marine-specification coatings for enhanced corrosion resistance.

Marine cylinders are widely used in:

Offshore and subsea machinery
Shipboard hydraulic systems
Marine winches and lifting equipment
Dredging and port operations
Energy and utility installations in coastal environments

They are particularly valuable in systems requiring robust, corrosion-resistant hydraulic power in extreme conditions.

We can supply custom-designed marine hydraulic cylinders tailored to your specific application and operating parameters.

Once you’ve submitted your design form, one of our hydraulic engineers will get back to you promptly to confirm your requirements in full.

Are marine hydraulic cylinders corrosion-resistant? Yes. They are supplied with marine-grade coatings and can be customised with plated or shotblasted finishes.

Can marine cylinders be integrated into existing designs? Absolutely! Our 3D design software allows models to be exported directly into your machine design.

Do marine cylinders undergo pressure testing? Yes! All subsea and marine cylinders are tested to 1.5x their designed working pressure.
