Abstract
The present invention relates to seals and, in particular, to a seal that retains lubrication between the interface of a spline shaft and a sleeve shaft, which move relative to each other. The seal body has a flexible body with an axis and alternating projections and recesses aligned with the axis. A wiper element on at least one of the rows of projections and alternating recesses includes a tapered surface extending away from the axis, and an engagement face substantially perpendicular to the axis and adjoining the tapered surface.
