Special materials for plain bearings

Plain bearing manufacture

Sliding elements of the most varied shapes are produced from this composite by cutting, punching and forming. Flange bushings composed of wrapped bushes and punched thrust washers are joined by applying a newly developed laser welding method and boast a series of benefits compared to the standard forming process. Depending on each specific case of application, at the end of the process a fine-tuned corrosion protection treatment is performed

Quality

The entire production process is monitored and controlled by means of a close-meshed net of quality assurance measures, thus ensuring process reliability of all important plain bearing characteristics.
