Beschreibung
Zusammenfassung:	The utility model relates to an automatic core-positioning combined gasket, which comprises a zinc coating layer, a sealing lip and a rubber layer, wherein the sealing lip is adhered and fixed on the inside of the metal zinc coating layer and the rubber layer is adhered and fixed on the inside of the sealing lip. In an inner ring of an original production, the rubber layer for automatic core positioning is added, so that the automatic core-positioning combined gasket in the utility model has the automatic core-positioning function. The automatic core-positioning combined gasket in the utility model is directly positioned on a screw and a bolt, so that installation becomes more convenient, rapid and efficient; and troubles and product cost generated from a customer's demand for processing a positioning groove are reduced.
