ABSTRACT:
A sliding bearing, particularly for slippers of hydrostatic piston machines, with a support having a supporting surface on which slides a sliding piece having a sliding and sealing surface. Between the supporting surface and the sealing part of the sliding and sealing surface is a bearing gap height (h.sub.2) and in the sliding and sealing surface at least one shallow recess with a depth (h) bordered by the sealing part of the sliding and sealing surface. At least one connecting channel is connected to a pressure source of the lubricating fluid so that a lubrication gap with a height (h.sub.2 +h) is formed. The lubrication gap is in accordance with the invention designed in such a way that a self-adjusting load bearing capacity dependent on the gap height (h.sub.2) is achieved, whereby in the gap such a flow is created, under the influence of which the velocity of the lubricating fluid is positive (greater than zero) in all directions and the pressure gradient is declining in the flow direction.
