Editor’s pickIgus expands plain bearing range with iglidur E7


With specification such as low coefficient of friction and enhanced vibration dampening, the tribo-polymer iglidur E7 provides strengths in the sliding elements of the drylin linear technology from igus. It further allows users to benefit from iglidur E7 mechanisms with rotating or pivoting movements.

In times of advancing automation of the industry, durable, cost-effective and energy-efficient machine components are called for. Since 1983, igus has been developing tribo-polymers for plain bearing technology that are free of lubricants. To date, the company has a total of 57 iglidur materials in its product range for various applications.

Tribo-polymer has been used in the sliding elements of drylin linear systems since 2012, and has been available in dryspin lead screw nuts since 2018. The vibration-dampening specifications of the tribo-polymer has allowed the equipment to be employed in applications such as camera lenses, train doors and 3D printers.

Building upon these successes, igus further developed the material for its plain bearing range. The iglidur E7 is designed for low to medium loads in pivoting movements and withstands surface pressures of up to 18MPa in motion.

Stefan Loockmann-Rittich, business unit manager of iglidur plain bearing technology, igus, said: “Due to the very low coefficient of friction of the iglidur E7, the drive energy is reduced, saving costs for the user.”

The new plain bearing material can be used for flap and sensor bearings. Further applications are found in packaging, textile machinery and furniture technology.

Iglidur E7 is currently available as a plain bearing in 12 standard dimensions. Further dimensions and customised designs according to customer specifications are available as well. Even special parts can be produced by injection moulding from tools made in the conventional or print-to-mould method as well as from the appropriate bar stock.
