Abstract
A seal includes an annular mounting portion having an axial leg extending axially from the annular mounting portion toward the air side. A radial leg portion extends radially inward from an end of the axial leg. A lay down sealing lip extends radially inward and axially toward the oil side from an end of the radial leg portion. A dust lip extends from the end of the radial leg portion in a direction opposite the lay down sealing lip. When the oil side is under negative pressure and when the lay down sealing lip begins to lift radially off the shaft, there is a counterbalance force applied to the axial leg that is designed to be flexible enough that the oil side vacuum “rocks” the seal bringing the dust lip into contact with the shaft and blocking airflow.
