ABSTRACT:
A cassette seal for sealing off the gap between a bore hole and a shaft. The seal includes an inner ring which is secured to the shaft and has a groove open radially to the outside. The seal also includes an outer ring secured in the bore hole with a radial projection of a flange-type design that engages with the groove. The groove is defined in the axial direction by end faces turned toward each other. A sealing lip secured in the area of the inner circumference to the radial projection is formed from a polymer material. At least the inner ring is formed from a plastically deformed sheet metal. The sealing lip sealingly contacts the inner ring in the area of one end face. The inner ring is designed in one piece and is provided in the area of both axial ends with ring projections, which are produced by a plastic deformation and project radially to the outside. The outer ring is limited bounded in the axial direction on both sides by range spacers formed from a polymer material. The range spacers are set apart in the circumferential direction and abut on the end faces when the cassette seal is new and unused.
