H4 Marine have been supplying systems and components to a wide range of vessel operators and builders for over four years.

H4 supplies truly innovative and effective systems and components, we are focused on the marine market but are also suppliers to a number of other engineering disciplines. The bearing material has been of particular interest to those already using or considering composites who are looking for a premium product.

If you have requirements or simply questions that relate to marine shaft systems or bearing performance/failure analysis we can probably help or will know someone who can. Our role often starts with problem solving but always ends in a solution.

Our customers include more than one Navy, as well as custom builders of luxury yachts of 50m and more. Shaft sizes to greater than 200.00mm (8") and bearings to over 0.5m (22") diameter.

Within the companies whose products we supply there is a very broad range of knowledge we can call on, covering composite engineering, hydraulic systems, materials technology, vibration and noise reduction, bearing systems and power transmission. These companies and their respective experts in their fields have been in operation for more than 10 years.
