Abstract

A rack may include a toothed portion having a toothing, and a shaft portion having a threaded portion with a coaxial thread that has a thread length in an axial direction of a longitudinal axis. Separate segments comprising at least one in each case bar-shaped toothed segment and one shaft segment are provided, are aligned on the longitudinal axis, and are connected to one another at a joint. A method for producing the rack may involve providing a shaft raw material piece having a piece length that is a multiple of a shaft segment length, generating a thread that is continuous in a longitudinal direction on the shaft raw material piece across a multiple of the thread length to produce a threaded semi-finished product, cutting to length a threaded segment from the threaded semi-finished product, providing a toothed segment, and joining the threaded segment to the toothed segment.
