Abstract
In order to cool the slide bearing area for the slidable bearing of a gear pump shaft, a slide bearing bush with a slide bearing area and, in the case of the guiding-through of a shaft, a sealing area extends in one piece integrally to the outside, and a cooling-medium guiding system provided in the bush is connected from the outside. This eliminates all sealing problems for the cooling medium feeding to the slide bearing area.
