Abstract

The invention relates to a camshaft, especially for motor vehicle engines, comprising a hollow outer shaft (1) and an inner shaft (2) arranged coaxially in the outer shaft (1) and mounted in such a way that it can rotate in relation to the outer shaft (1). Said camshaft also comprises first cams (3a) arranged on the outer shaft (1) in a rotationally fixed manner, and second cams (3b) that are arranged on the outer shaft (1) and fixed to the inner shaft (2). According to the invention, a supporting element (7) is provided on at least one of the end regions of the inner shaft (2), said supporting element projecting past the outer shaft (1) in the radial direction. An outer peripheral surface (8) of the outer shaft (1) and an associated inwardly facing surface (9) of the supporting element (7) form a radial bearing.
