Camshaft adjuster for adjusting and fixing the phase position of a camshaft of an internal combustion engine in relation to a phase position of a crankshaft, comprising:
- a timing gear which is driven by the crankshaft,
- an output part which is secured on the camshaft, attached to the camshaft or to an extension of the camshaft and is driven by the timing gear via a hydraulic actuating drive,
- the actuating drive comprising at least one pair of hydraulic pressure chambers operating towards each other, and
- the pressure chambers being supplied with pressure medium via a pressure medium distributor and pressure medium lines,
- the pressure medium distributor and the camshaft adjuster together with a component secured on the cylinder head form a camshaft axial bearing
- the camshaft or the extension of the camshaft protrudes over the output part in an axial direction on a side of the camshaft adjuster which faces away from the cam.
