JDMA is sealed by a combination of a double lip elastomer and a wear ring. The sealing lip protrudes outward before installation, and the cylinder liner is pressed after installation to provide elastic force to the wear ring, which can achieve excellent sealing even without pressure. It can be used in mineral oil, modified oil, flame retardant hydraulic oil and compressed air to separate the liquid on both sides of the seal ring. It is also suitable for the sealing of the oil chamber to prevent the invasion of other liquids.
