Abstract
A sealing element for a shaft coupling is disclosed. The sealing element may include an annular seal body and a plurality of projections circumferentially spaced around the seal body. One or more of the plurality of projections may include at least one of an axial component extending longitudinally in an axial direction from the seal body and/or a radial component extending radially inwards from the seal body towards the center axis. The sealing element is configured to retrofit into existing standard o-ring grooves and provides optimal lubrication, for example in a spline joint, by keeping the spline joint contact area submerged in lubricant and includes heat and debris removal with lubricant flow-through.
