shaft and seals axially against a stationary counterface perpendicular to the shaft. This type of
seal has been used widely for several applications and has proved to be reliable and effective
against dust, dirt, water and oil splash and other media.
The ring consists of three parts:
a) The seal body, installed with interference to the shaft.
b) The hinge, acting as a sprung connection between the body and the lip.
c) The conical and flexible sealing lip which provides the actual dynamic sealing against the
counterface.
The counterface can be the side wall of the bearing, a washer or any housing.
