NEw RANGE Of PLAIN BEARINGS mEETS AUTOmOTIvE INDUSTRy DEmANDS BEARINGS, SEALS & GASKETS
Plain bearings are used in a range of applications within the automotive industry, from the chassis or transmission to windscreen wipers and convertible roof systems. However, the bearings need to be robust, durable and corrosion-free, and many plain bearing materials reaching their limits here. To help, igus is launching plain bearings made of the new high-performance plastic iglidur H5. iglidur H5 is the fifth generation of the iglidur H
family. Rob Dumayne, head of the dry-tech business unit at igus UK, commented: “Long term tests at our in-house laboratory have shown that iglidur H5 is up to 30% more wear resistant than its predecessor H4.” This was achieved by further optimising the polymer formula. iglidur H% has significantly improved impact strength and elasticity, and this complements the other materials of the H-family, which are fibre- reinforced, especially for higher loads, and are relatively stiff and less forgiving. iglidur H5 is also resistant to high levels of force, but significantly tougher than, for example, iglidur H3 and H4. The new iglidur H5 plain bearings can be used in
a range of applications in the automotive industry, including the operation of windscreen wipers. They must function reliably under high loads – for example, with a fully snow-covered windscreen. The company has therefore added fibres and fillers to the base polymer which enable the plain bearings to withstand high forces and edge loads as well as impacts and shocks, even under continuous stress.
In addition, the material is resistant to road salt,
chemicals, fuels, oils, and high temperatures of up to 200˚C. This also makes it suitable for use in engine components – for example in water and coolant pumps. “With iglidur H5, we have created an enhanced material with which we are now prepared for current and future requirements of the
automotive industry,” Dumayne explained. However, the new polymer plain bearings are also applicable for pumps used in chemical plants and other industrial applications outside the automotive sector.
