Steering knuckle bushings are not only exposed to high forces but also to various kinds of movements that affect the bearing, from small vibrations when driving up to jolting movements where vehicles are driven on construction sites or operate in quarries. At the same time good mobility of the steering knuckle pin is required in any of these situations.
For years it has been our experience that machined bushings made of Wieland-S40 (PDF, 29 KB) and wrapped bushings made of Wieland-B09 (PDF, 29 KB) are the ideal materials for this purpose. Bushings and washes can be adjusted to constructive needs and therefore perfectly matched with the vehicle. Wieland would be happy to design the necessary bearing for your requirements.
