ABSTRACT:
A self aligning die guide pin bushing incorporates inner and outer sleeves that are axially locked together, but which can shift radially relative to one another sufficiently to accommodated an eccentricity between the guide pin and the bore in which the bushing is mounted. The outer sleeve of the bushing is mounted to the bore conventionally, and is removable. After the outer sleeve is mounted, the other die is moved so as to push the guide pin through the inner sleeve, thereby forcing the inner sleeve into alignment with the guide pin. Then, an epoxy layer is injected into the spaced between sleeves to fix the inner sleeve in alignment with the guide pin.
