Selection by Characteristic Values Wear                    Wear of friction bearings depends on a number Test parameters: of influence factors, such as the load, speed, temperature, and contact pairing. Therefore, it is all the more important that the optimal bearing for the application is selected. The wear rate of food-compatible friction bearings made of Moldflon™ is several factors lower than that of typical commercial all-plastic friction bearings.
