Abstract
A pivot bearing () for a hydraulic clearance compensation element (), especially of a valve train of an internal combustion engine, is provided in which the pivot bearing () has a first part () projecting in an axial direction (a) with a surface () that is convex at least in some sections and also a second part () with a surface () that is concave at least in some sections for at least partially holding the first part (). To optimize the production of such a pivot bearing and to minimize the associated costs, the invention provides that the first part () is constructed at least partially as a ball, wherein the second part () surrounds the ball () with undercut in the axial direction (a).
