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.
The Iglidur N54 plain bearing from Igus is based on 54 per cent sustainable and natural raw materials. The basic polymer is mainly made of castor oil rather than finite crude oil. This biopolymer is suitable for universal use in the low-load range, as well as in industrial and consumer goods applications
When looking to replace expensive PTFE-lined metal bearings in its home theatre, gaming and cinema seats, D-Box Technologies — a designer and manufacturer of sophisticated motion systems for the entertainment industry — approached Igus. The seats use three types of intelligent movement — subtle pitch, roll and heave — to move the occupant gently forwards and backwards, from side to side, and up and down.
Igus has developed the Young Engineers Support (YES) programme in order to share its extensive knowledge with engineering students and lecturers across various UK colleges and universities. The initiative aims to provide students and lecturers with free product samples and reference materials tailored to their needs — for lectures, presentations and projects — while offering them the opportunity for sponsorship and to talk to Igus’s specialists.
At this year’s Interplas exhibition at the NEC in Birmingham, taking place between 30 September and 2 October 2014, Igus will present food-grade Tribo tape, maintenance-free plain, spherical and linear bearings and self-lubricating energy chains and Chainflex cables.
