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’s iglidur g bearings have been used in the NOAH (Normally Operated Articulated Hybrid) suspension system, designed by handmade bicycle specialist COFA Engineering.
igus has developed robolink, a multi-axis joint for humanoid robots and lightweight automation applications. A complete modular system, robolink is suitable for use where masses are to be kept as low as possible.
igus has retrofitted a car’s conventional bearings with iglidur plain bearings and circumnavigated the globe to demonstrate the durable and robust nature of iglidur materials in harsh environments, from dirt tracks to wet and humid locations.
According to bearing specialist igus, by switching to igus drylin linear bearings, design engineers will be able to see potential weight savings. By replacing a typical steel shaft and steel linear bearing with an igus RJMP bearing and hollow aluminium shaft, the company says that the weight reduction of the system can be as much as 85 per cent.
