An internal support interface which provides vibration and acoustic isolation. A stationary shaft has a medial portion about which a rotatable member rotates. An end portion of the shaft has an annular base surface surrounding a stub shaft projection. A substantially planar housing member has a support post which extends from an annular interior surface in adjacent, non-contacting proximity to the stub shaft projection to form a gap therebetween. An annular damping member mutually contactingly surrounds the stub shaft projection and the support post while being compressed between the base surface of the shaft and the interior surface of the housing member.
