A vibration isolator comprising: a housing having an upper portion including a top surface, a bottom portion having an inwardly extending protrusion and a bottom surface and a hollow interior; a sleeve having a hollow interior, an upper cylindrical portion and a lower flanged portion extending substantially perpendicular to the upper cylindrical portion, the lower flanged portion having a top surface and a bottom surface; a resilient core defined by: first; second; and third annular surfaces and two transitional surfaces (190, 191) in which one transitional surface extends inwardly and radially from the upper cylindrical portion to the second annular surface, and the other transitional surface extends radially outward from the second annular surface to the third annular surface, in which the second annular surface and the two transitional surfaces (190, 191) correspond to the inwardly extending projection of the housing, the resilient core having a hollow interior, positioned between and fixedly coupled to the bottom portion of the housing and the top surface of the lower flanged portion of the sleeve, a portion of the resilient core and the sleeve extending outwardly from the bottom portion of the housing wherein the lower flanged portion of the sleeve extends outwardly via a transitional portion which is defined by an outwardly tapered conical surface between the upper cylindrical portion and the lower flanged portion or a ninety degree angle between the upper cylindrical portion and the lower flanged portion, the inwardly extending protrusion of the housing engaging an outer surface of the resilient core; a first bushing disposed within the interior of the sleeve, the first bushing having a flange including a bottom surface that overlays a top surface of the resilient core; and a second bushing disposed within the first bushing. a housing having an upper portion including a top surface, a bottom portion having an inwardly extending protrusion and a bottom surface and a hollow interior; a sleeve having a hollow interior, an upper cylindrical portion and a lower flanged portion extending substantially perpendicular to the upper cylindrical portion, the lower flanged portion having a top surface and a bottom surface; a resilient core defined by: first; second; and third annular surfaces and two transitional surfaces (190, 191) in which one transitional surface extends inwardly and radially from the upper cylindrical portion to the second annular surface, and the other transitional surface extends radially outward from the second annular surface to the third annular surface, in which the second annular surface and the two transitional surfaces (190, 191) correspond to the inwardly extending projection of the housing, the resilient core having a hollow interior, positioned between and fixedly coupled to the bottom portion of the housing and the top surface of the lower flanged portion of the sleeve, a portion of the resilient core and the sleeve extending outwardly from the bottom portion of the housing wherein the lower flanged portion of the sleeve extends outwardly via a transitional portion which is defined by an outwardly tapered conical surface between the upper cylindrical portion and the lower flanged portion or a ninety degree angle between the upper cylindrical portion and the lower flanged portion, the inwardly extending protrusion of the housing engaging an outer surface of the resilient core; a first bushing disposed within the interior of the sleeve, the first bushing having a flange including a bottom surface that overlays a top surface of the resilient core; and a second bushing disposed within the first bushing.
