Abstract
A slide bearing for a gear pump or the like has a lubrication groove provided in the surface of the cylinder forming the slide bearing. The lubrication groove is constructed to be ending flatly in the area of that edge which, with respect to the shaft rotating direction acts as an inlet edge into the slot between the slide bearing and the shaft. Thus, it is achieved that the slide bearing is sufficiently lubricated also by fluid which flows at a higher viscosity and has an unknown elastic performance.
