Abstract
A shield device prevents materials from contacting a seal for a shaft extending outwardly from a housing and displacing a mounted component. The shield device includes an annular disk having opposing first and second radial surfaces and outer and inner circumferential edges, the inner edge defining a bore for receiving the shaft. The disk is coupleable with the shaft so as to be disposed between the component and the housing and is spaced axially above the seal such that the first radial surface faces the seal. The disk has an outside diameter greater than the seal outside diameter and overlaps the seal with the disk outer edge being spaced radially outwardly from the seal to provide a barrier about the seal. Preferably, an annular projection extends axially outwardly from the first, lower radial surface and is disposeable within a circular groove of the housing that extends about the seal.
