The company igus has expanded its wide range of iglidur round bars by no less than four materials; among them two for the food sector: the heat-resistant material iglidur AC500 and the resilient material A250. The extremely hard-wearing material iglidur H3 and the particularly wear-resistant endurance material iglidur E complete the product range. This makes it possible to mill and turn lubrication-free and maintenance-free prototypes and special components for a wide variety of applications.

For the production of special bushings, rollers and other sliding elements that come into contact with food, igus has developed iglidur AC500 – an FDA-compliant high-temperature material for the food industry that withstands extreme temperatures of up to 250°C. Thus, components made of AC500 are suitable, among other things, for sliding elements in baking lines. When a plain bearing made of AC500 rotates on a high-grade stainless-steel shaft, wear is only 0.16 micrometres per kilometre, as tests in the in-house test laboratory showed. In addition, the material has exceptionally high chemical resistance, so that it reliably withstands cleaning agents common to the food industry. Lubrication is not necessary in this case. A double advantage, as the risk of contamination and the maintenance effort are reduced.

Knife edge rollers made of iglidur A250 reduce energy consumption

The new iglidur A250 round bars are also predestined for the food and packaging industry. They are suitable, among other things, for the production of so-called knife edge rollers, which are used in the deflection of conveyor belts. In this function, the material reduces the drive power required and the energy consumption of the belts thanks to its low-friction, lubrication-free dry operation. In addition, the material impresses with its high load-bearing capacity. iglidur A250 is designed in such a way that it can be used for high belt speeds in the food and packaging industry. And just like AC500, A250 also has the approval for direct contact with food. The material complies with the hygiene guidelines of the US Food and Drug Administration (FDA) and EU Regulation 10/2011.

iglidur H3 withstands aggressive media

The H3, a material from which media-resistant components can be manufactured, has also been added to the iglidur bar stock product range. iglidur H3 was developed primarily for contact with aggressive media and the application in pumps, for example in fuel pumps. The material works reliably in these extreme applications thanks to its durability and low moisture absorption combined with a long service life.

iglidur E improves precision movements

The fourth new material is iglidur E. Among other things, this is used to manufacture plain bearings that dampen vibrations in combination with aluminium shafts. This specification improves precise and smooth movements of machines and equipment. The material also shows excellent wear properties in linear pivoting movements in the textile industry, packaging industry, printing industry and vending machinery.
