Since 2008, we have been working on bearing solutions for main gearboxes on wind turbines that are already in series production. During a detailed design process, we develop customer-specific and application-driven plain bearing solutions. Power density can be increased even further in future by integrating the bearing functionality into the component using a direct coating. The question of plain bearing vs. roller bearing does not arise here.

As the Bearing Division, we combine the competencies of engine plain bearing technology and industrial plain bearing technology. For engines, we deliver an impressive range of materials expertise for a high load range at moderate speeds. For turbines and compressors, we deliver plain bearing technology as opposed to roller bearings based on broad design expertise for very high circumferential speeds. Our interdisciplinary technical and application knowledge enables us to offer bearing solutions for a variety of applications with a wide range of specifications. So plain bearings will be able to replace roller bearings in other industries as well over the long term.
