Polymer researcher and bearings specialist igus UK has developed a plain bearing material that is based on 54% sustainable and natural raw materials. 


10/13/2011 — At this year’s Interplas exhibition at the NEC in Birmingham, igus UK  unveiled its new environmentally-friendly biopolymer bearing material, iglidur® N54. Based on 54% natural, renewable resources, the new material is green in colour to reflect its credentials. Suitable for use in bearing applications with operating temperatures of between -40 and 80°C and accommodating medium loading conditions, the material fits well into the mid-range of the iglidur family.

 Available in both sleeve and flange styles, typical industry sectors for iglidur N54 would be consumer products, as well as general mechanical engineering, furniture manufacturers and industrial design. As well as having universal applications, and being free from any maintenance or lubrication regimes, the main benefit of this material is that it is kinder to the environment.

The basic polymer of the new iglidur N54 plain bearing is mainly made of castor oil, rather than finite crude oil. The company’s mechanically and tribologically optimised biopolymer is suitable for universal use in the low-load range.

As with all igus iglidur polymers, iglidur N54 is a high-performance tribological plastic material that is both lubricant and maintenance free. In-house test results indicate excellent wear resistance properties with loads up to 2MPa, thus a green alternative for general purpose, low-load applications.

As well as general industrial applications, igus sees possibilities for the biopolymer in consumer goods, for example furniture and other items of daily use.

The new bio-bearing fits well within the igus concept of developing environmentally-friendly alternatives for applications that currently work with lubricated metallic plain or roller bearings. iglidur N54 bearings are self-lubricating.
