Abstract:
A circumferential seal for a machine having a rotating shaft is provided. The seal may comprise a metallic mounting element and a ceramic sealing runner. The mounting element may be affixed around the shaft and comprise a base and a mounting member. The mounting member may extend radially outward from the base and axially along the shaft to form a radially inward facing cylindrical surface. The sealing runner may have a radially outward facing surface and be carried by said mounting element in axial and radial alignment by an interference fit between at least a portion of the radially outward facing surface of the runner and at least a portion of the radially inward facing surface of the mounting member.

Claim (Index 14):
A circumferential seal for a machine having housing and a rotating shaft, said seal comprising:\n a mounting element affixed around a circumference of the shaft, said mounting element comprising:\n a base forming a radially outward facing surface extending axially along the shaft and a radially inward facing surface extending at an angle relative to an axis of the machine, said radially outward facing surface defining a groove for engaging a flexible sealing element; and \n a radially compliant mounting member comprising an extension projecting radially outward from the base, an arcuate, axially extending member and an axial return member forming a radially inward facing cylindrical surface, \n a sealing runner having a radially outward facing cylindrical surface extending axially along the shaft, said sealing runner being carried by said mounting element in axial and radial alignment by an interference fit between at least a portion of said radially outward facing cylindrical surface of said sealing runner and at least a portion of said radially inward facing cylindrical surface of said mounting member proximate to an axial end of said sealing runner; and a carbon radial seal engaged with the housing, said carbon radial seal having a surface sealingly engaged with said radially outward facing cylindrical surface of said sealing runner.
