The invention relates to a sealing bellows for balljoints, driveshaft connections and similar, characterized in that the wall of the sealing bellows comprises at least two layers of elastomer or polymer (5, 6) with differing material properties. According to the invention, the multi-layer construction of a core and main layer permits materials not previously applicable to the production of sealing bellows to be used for the above purpose. Furthermore, the differing quality-determining factors of, for example, elasticity and surface properties of sealing bellows can be essentially independently optimised. Sealing bellows with optimal quality properties can thus be produced at low cost. |
