When an excavator moves hundreds of kilograms of sand or an agricultural tractor lifts square bales, enormous loads act on the bucket and fork bearings.
Until yesterday, the plain bearings designed to support these efforts were made of metallic materials or different synthetic materials combined together through a winding process. In any case, the bearings were expensive and if metallic they also required periodic lubrication. Thanks to constant advanced investments in research and development, the German Igus group has today managed to create a bearing with performance characteristics superior to those of synthetic bearings, but made using injection moulding, a process which allows minimizing production costs. production. “Iglidur Q3E”, this is the name of the product, is the first heavy-duty plain bearing obtained through injection molding despite being composed of two different layers of high-performance plastics.
The first layer, the external one, ensures the possibility of withstanding maximum dynamic surface pressures of 75 MegaPascals, approximately 765 kilos per square centimeter, while the internal core, tribologically optimized, guarantees low friction and durability over time without the need for periodic lubrication That. This is because it incorporates solid lubricants which are released gradually throughout the entire operating life. It should be noted that the bearings are presented for use as monolithic components as Igus has managed to machine the two different components so that they become one, fully exploiting the advantages and properties of both. This is thanks to very sophisticated and latest generation multi-component injection molding systems.
Minimize maintenance needs
Designed with a specific focus on construction and agricultural machinery, “Iglidur Q3E” helps to minimize the maintenance needs of agricultural and construction machinery and related equipment. It should be noted that the Igus brand is owned by a family-run company based in Cologne, Germany, which operates globally thanks to 31 branches in as many countries and approximately five thousand employees throughout the world. In 2023 it achieved a turnover of one billion and 136 million euros, benefiting from components made up of over 243 thousand items and usable in the most disparate industrial sectors.
