The Spring ensures that the Sealing Lip maintains contact with the shaft surface, even as the shaft moves up and down due to engine vibrations.Attributes:• Withstands maximum and normal shaft speeds of 2000 rpm and 1340 rpm• Withstands maximum and normal oil operating temperatures of 250 °F and 220 °FApplications:A Lip Seal is used to create a secure and tight seal around the engine crankshaft, effectively preventing oil leakage and maintaining the necessary lubrication for the engine components.
