ABSTRACT:
According to the present disclosure, a sealing assembly may include a first member, a second member, and a circumferentially extending seal. The first member may include an angularly disposed running surface. The second member may be rotatable relative to the first member about an axis of rotation. The circumferentially extending seal may be coupled to the second member. The seal may include a lip having a first end fixed to the second member and a second end being generally free. The first end may form a hinge generally providing for radially outward movement of the second end relative to the axis of rotation upon rotation of said second member. The second end may be biased against the running surface.
