A bearing assembly includes an annular inner member defining a first outer surface and a first inner surface, and a shaft extending therefrom. The bearing assembly includes an annular outer member defining a second outer surface and a second inner surface which is adapted to engage a recess defined in the first outer surface. An annular flexible seal defines a base adapted to engage the outer member, a head adapted to engage a groove defined in one of the inner member or the shaft, and a neck having a curvilinear cross-section which is adapted to bias the base toward the recess and the head toward the groove. The flexible seal is positioned adjacent to one end of the outer member and extends between the inner member and outer member. An annular low-friction liner has a cross-section that defines an interior area adapted to engage the flexible seal head.
