Abstract
A cartridge seal is described where the outer ring 1 and the inner ring 4 are inseparably joined to each other. The outer ring has a circumferential groove 2 which is axially open in a direction toward the outside 14 and which is engaged by a first and second sealing lip of the inner ring 4. The second sealing lip 9 is formed by an extrusion of the protruding end of the first sealing lip 8. Both sealing lips 8, 9 contact their corresponding counter surfaces 6, 7 with circumferential sealing edges 10, 11.
