Abstract
A method for producing a shaft, in particular a balance shaft, crankshaft and the like, having at least one substantially annular bearing seat and at least one unbalance portion. The method includes the steps: provision of a shaft blank; formation of the at least one unbalance portion and of at least two opposite bearing seat side members by a forming process; and deformation of the at least two opposite bearing seat side members by a shell tool such that the bearing seat side members are bent together, whereby the at least one substantially annular bearing seat is formed.
