Abstract

An adjustable camshaft may include an inner shaft and an outer shaft disposed coaxial therewith. A first cam may be connected non-rotatably to the inner shaft, and a second cam may be connected non-rotatably to the outer shaft. At least two bearing elements may be connected fixedly to the outer shaft. The first cam may be disposed between the at least two bearing elements. The at least two bearing elements may fix the first cam in an axial direction relative to the outer shaft, and the at least two bearing elements via the first cam may fix the inner shaft in the axial direction relative to the outer shaft.
