Abstract: A camshaft and a method for manufacturing the camshaft as described. A gear wheel of the camshaft is mounted on a camshaft tube. A collar that is attached to the gear wheel and a locating bearing element that is mounted on the camshaft tube delimit a locating bearing seat of the camshaft.

Abstract: A method and an assembly system for manufacturing an assembled camshaft having a metallic shaft and at least one shrunk-on cam, includes initially heating the at least one cam, threading the at least one cam onto the shaft in a predetermined position in the heated state, and subsequently shrinking the at least one cam onto the shaft due to a cooling down. The shaft is cooled down prior to thread-on of the cams so that the cams are shrunk onto the shaft due to a temperature equalization which includes heating of the shaft and cooling down of the cams. The assembly system includes multiple drums in which the shafts and the cams to be fitted are accommodated and cooled and/or heated. The shafts are cooled preferably with the aid of a cooling lance inserted into a hollow space of the shaft.
