New iglidur bearings meet FAA’s fire safety compliance requirements



Treotham announces that five iglidur high-performance polymer bearings from igus meet the fire safety compliance requirements of the US Federal Aviation Administration (FAA) for aircraft interiors.

These iglidur plain bearings are used within aircrafts for bearing points in seats, tables and doors, with the maintenance-free range ensuring a light, safe and lubrication-free solution.

Aviation components are required to be lightweight, quiet and fail-safe, while components used in the interiors of airplanes also require compliance with strict fire safety standards. The igus plain bearing materials iglidur G V0, iglidur X, iglidur A350, iglidur H and iglidur J350 have now been positively tested by an independent test institute in accordance with the fire test FAR CS 25.853 App F, Part 1a 1 (ii).

The five plain bearing materials are also rated V0 according to UL94, making them the optimal solution for moving applications in aircrafts, for example, in fold-out tables, adjustable seats or in the hinges of doors and luggage compartments. With these five bearings, designers of interior equipment in aircrafts have suitable iglidur materials for all plain bearing applications: the cost-effective all-rounder iglidur G V0, the FDA-compliant iglidur A350, the iglidur J350 and iglidur H with exceptionally low moisture absorption, all the way to iglidur X, the high tech problem solver.

iglidur plain bearings, like all igus products, operate without external lubrication, thanks to the solid lubricants homogeneously engrained in the material to ensure silent and smooth operation. Users are able to minimise the maintenance work and costs associated with regular re-lubrication; reduce the effort required during assembly; and have the assurance that the components will always remain clean – an important criterion in aircraft interiors.

Key advantages of igus iglidur bearings include lighter weight (up to seven times) compared to metallic alternatives, which is crucial in the aerospace industry; cost savings in comparison with metal bearings; corrosion-free benefits; greater flexibility simplifying assembly and minimising noise; and ability to withstand impact and edge loads.
