Abstract
A dynamic seal assembly has an outer carrier member formed of one-piece having an outer flange, an inner flange, and an intermediate portion presenting first and second shoulders. A PTFE seal member is disposed about the second shoulder and is compressed axially by a case member which, while the PTFE seal is compressed, is staked to the carrier to secure the seal. The carrier has an axially outwardly facing annular pocket accommodating a foam dust excluder into which a flange of a wear sleeve extends to protect the PTFE seal from debris. Additionally, the seal has a clamping ring having an axially extending first leg providing a second mating surface radially inwardly and generally parallel to the first mating surface of the outer member. A second leg of the clamping ring extends radially inwardly and generally orthogonally from the first leg so that a seal member having an outer periphery forming a clamping surface can be fixed between the inner flange of the outer member and the second leg of the clamping ring. With the seal located between the members, an interlocking portion formed in and extending radially outwardly from the second mating surface and into the first mating surface retains the clamping ring in an axially stationary position.
