Maintenance-free bearings in switch device

The railway network is increasingly exposed to high loads as more and more people and goods are transported by rail. This also leads to higher loads on points. Components are therefore required that can withstand the constant load. This is why iglidur plain bearings and thrust washers made of high-performance polymers are used in switch devices. The service life of these plain bearings can be calculated with the help of free igus online tools.

A continuous function of the tongue device must be guaranteed despite weather and vibrations. iglidur plain bearings are ideally suited for this application. All iglidur materials contain incorporated solid lubricants that make additional lubrication and maintenance superfluous. They are also fully operational in heat and cold and corrosion-free due to their material composition. Due to the large-area load distribution of the iglidur bearings, they can be combined in switch devices with both soft and hardened shafts.
