Abstract
A camshaft contains a support tube, on which components including at least one cam are arranged at predetermined locations. The support tube extends at least partially through a hole in the components, and wherein a press fit is produced between the support tube and the components by hydroforming. Accordingly, at least one locally formed material formation is provided between the support tube and the hole. Via the material formation, the component is retained at the location in a desired orientation relative to the support tube in such a way that the support tube having the mounted components can be fed for hydroforming.
