A fluid pump for a motor vehicle includes a pump wheel which is co-rotatably connected with a driving device via a rotor shaft, and a shaft bearing system for the rotor shaft. The shaft bearing system includes a bearing receptacle having a support flange, and a first and a second ball bearing. The first and the second ball bearing are each fixed to a radial outside of the rotor shaft, are each axially shiftable within the static bearing receptacle, and are positioned at opposite axial sides of the support flange. An outer race of the first ball bearing contacts the support flange. An outer race of the second ball bearing is axially preloaded away from the support flange via a preload spring. The first and the second ball bearing are each radially supported within the static bearing receptacle only by an elastic support ring which radially surrounds the outer races.
