Beschreibung
Zusammenfassung:	The present invention relates to a bearing bushing (1) for internal combustion engines, which bushing (1) is made from the combination of a layer (4) deposited by cathode sputtering with a sliding layer (5) composed of a polymeric matrix, and which improves the load-carrying capacity and seizure resistance properties to values higher than 120 MPa and 85 MPa, respectively, achieving a material index (MI) higher than 170 MPa.
