More Information
Summary:The utility model relates to a dust-proof seal ring, which comprises a support ring and a dust seal. The support ring is made of engineering plastics, and the dust seal is made of PU or rubber; an injection connecting hole or fastened projections are formed on the support ring; and the dust seal and the support ring are connected into a whole through injecting or fastening. The utility model has the advantages that the support ring adopts engineering plastics, so as to have the characteristics of hydrolytic resistance, oil resistance, high temperature resistance, low temperature resistance, and oxidation resistance; the support ring is one-time formed through injection molding, so as to achieve high processing efficiency; and the support ring has special structural design, so that the dust seal and the support ring can be tightly combined without adhesive, thereby realizing convenient and fast processing.
