A wicket gate mounting for the individual wicket gates of a water turbine includes a respective bottom stem for the wicket gate. The mounting includes a conically tapered inner bore of an outer bushing and a cooperating, complementary, conically tapered outer surface of an inner bushing. The inner bushing is longitudinally slit. The inner bushing is connected to a ring disposed at one end which has an axial surface facing toward an axial surface on the end of the outer bushing. Between the axially facing surfaces at the ends of the inner and outer bushings is disposed an axially adjustable alignment ring for adjusting the axial positions of the inner and outer bushings with respect to each other which adjusts the bearing play between a layer of slide bearing material inside the inner bushing and the wicket gate stem. The axial thickness of the alignment ring is adjusted, e.g. by being reduced in thickness so that the inner bushing is pressed further into the stationary outer bushing. The outer and inner bushings with the alignment ring in place are fastened together.
