Abstract
Described herein is a system for increasing the robustness of a sealing surface and eliminating an expensive plating operation. The system includes an axially rotatable object comprising a first material that is subject to corrosion. The system also includes a radial shaft seal positioned radially outward from the axially rotatable object. The system also includes a sleeve coupled to the axially rotatable object, positioned between the axially rotatable object and the radial shaft seal and comprising a second material that is corrosion resistant.
