Claims17
A sintered powder metal insert for being overmolded by an overmolding material, comprising a body of sintered powder metal, the body having opposed end surfaces and an outer surface extending between the end surfaces, the outer surface having one set of retention features formed in it as spaced apart recesses extending from one end surface toward the other end surface and terminating short of the other end surface and having a second set of retention features formed in the outer surface as spaced apart recesses extending from the other end surface toward the one end surface and terminating short of reaching the one end surface, the first set being angularly offset from the second set so that the features of the first set are angularly between the features of the second set.
A sintered powder metal insert as claimed in claim 7, wherein the end wall is in a plane that is perpendicular to the axial direction.
A sintered powder metal insert as claimed in claim 11, wherein the bore has a non-round shape so as to be driven by a shaft.
