A Study of Dust Cover Seals for Ball Joint Application

From the analysis of observational results of the many dust cover seals to be used on passenger cars, it has become clear that the control of the seal design functions such as the working envelope (space available for seal side-wall), the contact face load of the sealing lip, the axial rebound load by the side-wall component, and the anti-ozone property of side-wall materials are necessary to maintain the sealing performance, and that the present dust cover seals satisfy needs requested by the costomers. Therefore, these characteristics should be sufficient when considering the designing of the seal.
