Abstract: A rotating group for a supercharger includes a driving shaft and rotor assembly including a driving shaft connected to a driving rotor. A driven shaft and rotor assembly include a driven shaft connected to a driven rotor. The driving rotor is in intermeshing engagement with the driven rotor to rotate in a pair of transversely overlapping cylindrical chambers defined in a rotor housing of the supercharger. A driving shaft bearing is disposed in a bottom plate to radially and axially support the driving shaft for rotating the driving rotor in the rotor housing at a first predetermined axial location of the driving rotor from the bottom plate. A driven shaft bearing is disposed in the bottom plate to radially and axially support the driven shaft for rotating the driven rotor in the rotor housing at a second predetermined axial location of the driven rotor from the bottom plate.
