1. A torsional vibration damper comprising:

  • a hub having a shaft-receiving member defining an axis of rotation and a plate extending radially outward about the shaft-receiving member, wherein the plate terminates with an annular outermost side devoid of a flange;

    a first portion of an inertia member defining a back face and a bore therethrough and having an annular flange concentric about the axis of rotation, wherein the shaft-receiving member of the hub is positioned in the bore with the plate of the hub spaced a distance from an interior surface of the annular flange, thereby defining a gap between the annual outermost side of the plate and the interior surface of the annular flange of the inertia member;

    a first elastomeric member and a second elastomeric member positioned against opposite sides of the plate; and

    a second portion of the inertia member fastened to the first portion of the inertia member by one or more fasteners thereby placing the first elastomeric member and the second elastomeric member in axial compression, wherein the first and second elastomeric members do not extend into the gap.
