Abstract
The specification describes two embodiments of a one-piece rear grease seal for an idler roller mounted on a shaft. Both embodiments comprise an annular lip in the shape of a truncated cone, an annular ring integrally connected to the larger end of the annular lip, and an annular web integrally connected to the outer end of the annular ring. In one embodiment, an annular groove is found on the annular ring to receive an axial end of an inner tube mounted concentrically about the shaft; the other embodiment does not have this feature.
