Abstract:
A radial lip seal arrangement defining a reference axis and being operative to seal the outer surface of a shaft to prevent leakage of fluid therebetween, the radial lip seal arrangement comprising:an elastomeric member having a body portion with a substantially linear peripheral surface oriented generally parallel to the reference axis, a radial surface substantially perpendicular to the reference axis, and first and second sealing portions spaced from each other along a line generally parallel to the reference axis, the first sealing portion includes a lip portion extending from the body portion and defines a recess between the lip portion and a portion of the substantial linear peripheral surface, the recess being positioned relative to the lip portion and the substantially linear peripheral surface so that the recess is interposed between the lip portion and the substantially linear peripheral surface, the lip portion has a radial surface that is generally perpendicular to the reference axis, the second sealing portion being formed by a first surface extending from the perpendicular radial surface of the body portion at an acute angle and a second surface that is generally perpendicular to the first surface; anda metal support member integrally attached to the body portion and having a first leg portion extending along the linear peripheral surface of the body portion and a second leg portion that extends along the perpendicular radial surface of the body portion and terminates at a location generally adjacent to the acute angled first surface of the second sealing portion.
