Abstract
A seal assembly includes an annular rigid support member having a centerline and including an axial portion coupleable with the outer member and a radial portion extending inwardly from the axial portion. The radial portion has an outer end formed with the axial portion and an inner end defining a central opening disposeable around the shaft and being formed asymmetrical about the centerline and/or having a varying radial distance from the centerline. An annular sealing member has an outer portion attached to the support member and an inner portion with a first end providing a sealing lip, the sealing lip sealingly engageable with a running surface about a shaft to define a sealing interface, and a second end attached to the inner end of the support member radial portion. As such, contact pressure of the sealing lip against the running surface varies about a circular perimeter of the sealing interface.
