ABSTRACT:
A process for improving the run-in characteristics of drives having sintered bearings. The drives are subject, prior to their operational usage in repeated cycles (I; II etc.), to a loading procedure exhibiting respectively a first load (M.sub.1), with the effect of operating of the sintered bearings in the mixed friction region (MR), and a following transition to a second load (M.sub.A, with the effect of operation of the sintered bearings in the boundary friction region (GR).
