Abstract: A bearing bush includes at least one sealing element and one bearing element. The sealing element is provided with at least one sealing lip. The bearing element is substantially tubular. The bearing element includes a plurality of protrusions extending in the axial direction on the outer circumference. The inner diameter of the bearing element is larger in the sections corresponding to the protrusions than in the remaining sections.

Abstract: A sealing body is for dynamic applications. The sealing body includes an elastomer material including epichlorohydrin rubber (ECO) as a rubber; and carbon nanotubes distributed in the elastomer material in an amount in a range from 0.4 to 10 phr, based on 100 parts by weight of rubber. The body has a Shore A hardness of in a range from 60 to 100.
