Abstract:
A bearing assembly is presented having a novel bearing seal design that, in one embodiment, combines the sealing advantages of both a labyrinth-like seal in combination with a contact seal. The seal is held perpendicularly to the sealing surface, and in one embodiment, substantially divides the sealing forces equally between the lubricant seal portion and the dust seal portion of the seal by virtue of the symmetry of the seal geometry and the application of the resisting force substantially along the seal body's centerline. The seal departs from the cantilever geometry of prior art seal designs, and in one embodiment, provides an inherently stiffer seal.
