H4 unveils Maritex Aquarius composite material
H4 Marine launched Maritex Aquarius composite bearing technology at Seaworks in Southampton and this material is now being trialled by navies and commercial builders.
The new grade has been developed to overcome some of the issues with marine growth reducing the life of bearings and shafts.
With seawater-lubricated shaft bearings, this is one of the main factors in system wear.
According to the company, Maritex Aquarius uses a unique structure and the surface finish of advanced polymers to help remove marine growth from the shaft.
The bearing structure also incorporates a surface chemistry that resists marine growth on the bearing itself.
H4 claims that Maritex has performed consistently better than other composites in a range of shaft, rudder and stabiliser applications, often reducing noise and vibration in the system.
H4 Marine will showcase Aqaurius, a new version of the composite Maritex bearing material, at this year's Seaworks show in June.
Plastic materials specialist igus will showcase a range of tribopolymer materials for the plastics design and moulding industry at this year’s Plastics Design & Moulding event.
A 1960s Morgan Plus 4 is competing in the Peking to Paris Motor Challenge next year. The iglidur tribo-tape from igus is playing a key role in this application.
Tribopolymer and plain bearing specialist igus UK has introduced a cost-effective plain bearing that is fire retardant and classified according to stringent UL94 with V0 fire regulations. As a result, OEMs can now benefit from a reliable bearing that operates safely over a long service life.
Polymer bearings specialist igus now offers 16 different tribopolymer materials in standard DIN ISO 3547-1 dimensions up to diameters of 50 mm. This amounts to over 13,000 plain bearings.
