Abstract
A bearing having to be assembled onto a shaft with a worm by passing over the worm where the diameter of the bearing section is larger than the outside diameter of the worm can be produced in a manner which saves material if not only the worm, but also the bearing section is non-cuttingly formed by rolling the basic material. It is possible to grind the bearing section at the outside, if necessary, and in an advantageous way, so that it is true to size and cylindrical.
