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.
igus is offering a range of bearing products that are blue in colour for easier detection in the food and drink industry. The iglidur A350 polymer plain bearing material is FDA approved (Food and Drug Administration, US) and the igubal polymer material can also be recognised by metal detectors; both materials are manufactured completely from tribo-optimised plastic.
iglidur bearings from igus have been fitted on all rotating shafts of the ‘Porton Man’ — a robotic mannequin developed by Crawley Creatures subsidiary i-bodi Technology to help the Ministry of Defence test chemical and biological (CB) protective suits and equipment for its armed forces — to enable fluid and friction-free movement.
igus is offering its range of dry-tech bearings for ultra-resistant furniture, which can be used in many home and office applications.
Tribo-polymer specialist igus has developed a structural plastic filament for use in 3D printing. The new tribo-filament is claimed to be up to 50 times more wear resistant than conventional plastic materials used for 3D printing.
