What do a car driving on a wet street, the loud creaking when a door opens, and the squeaking of train brakes have in common? Tribology plays an important role in all of them. Tribology is the study of friction, wear, and lubricants. Freudenberg does a lot of work in this area and is researching new materials, lubricants, and seals, to help reduce friction, wear, and with them the maintenance work to an absolute minimum. The approach is sustainable, particularly in sensitive industrial areas, as illustrated by a successful project for a power plant operator.
