A drive unit for a hybrid module includes a housing assembly and an electric motor including a stator and a rotor. The stator is fixed to the housing assembly. The drive unit further includes an assembly configured for rotatably connecting the rotor to an internal combustion engine The assembly includes a shaft configured for connecting to the internal combustion engine, a rear ball bearing on the shaft and a bearing housing on an outer race of the rear ball bearing. The bearing housing axially abuts the rear ball bearing so the rear ball bearing limits rearward axial movement of the bearing housing relative to the shaft. In other words, axial thrust from the bearing housing is transferred to the shaft by the axial load carrying capacity of the ball bearing.
