Challenges from real life: from rattling and squeaking seats
We have developed the iglidur K250 clip bearings for this purpose.
A challenge that not only automotive manufacturers face: cost pressure, mass production and increasing demands regarding quality and feel have to be brought in line. They have to produce elegant surfaces as cost-effectively as possible and realise clear lines and shapes. At the same time, moving parts should work without any sort of rattling (i.e. bearing clearance) and squeaking. In other words: the perfect user experience. This applies not only to vehicles, but also to kitchen devices or furniture.
One problem: the manufacturing processes often set additional requirements for the plain bearings. A mixture of bad installation tolerances in stamped sheet metals, high assembly forces as well as hot temperatures and aggressive chemicals during painting in immersion baths will break any metal plain bearing. Either the outer steel base layer rusts or the sensitive PTFE sliding film is damaged. The result: rattling and squeaking.
