Abstract
A bushing can include a load bearing substrate having a first major surface, an adhesive film overlying the first major surface, and a friction reducing layer overlying the adhesive film. A method can include extruding an adhesive film, laminating a friction reducing layer to a load bearing substrate with the adhesive film therebetween to form a composite, and shaping the composite to form a bushing. The adhesive film can include a first adhesive layer, such as and a fluoropolymer layer. The adhesive layer can include a modified ethylene tetrafluoroethylene, and the fluoropolymer layer can include an ethylene tetrafluoroethylene.
