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.
