Abstract

The invention relates to a process for producing a rolled bush from a planar bush plate which exhibits, on a first end surface, a peg-like protrusion which, in the rolled state, engages into a clearance in a second end surface, the shaping of the protrusion and of the clearance being matched to one another such that waste-free production of the bush plate is possible. The process is characterised in that, during the rolling operation, a fit for the protrusion and the clearance is produced, which fit is based on an essentially radial deformation, with respect to the longitudinal axis of the bush, of the protrusion and the clearance.
