Description

Technical Field

[0001] The utility model relates to the technical field of sealing rings, in particular to a high-efficiency O-type double sealing ring. Background Art

[0002] The rubber seal is an annular cover composed of one or more parts, fixed on a ring or washer of the bearing and in contact with another ring or washer or forming a narrow labyrinth gap to prevent lubricating oil leakage and foreign objects from intruding. O-rings are mainly used for static sealing and reciprocating motion sealing. When used for rotary motion sealing, they are limited to low-speed rotary sealing devices. Existing conventional structural products, no matter how the mold is opened, have high mold costs and low production efficiency. There are parting surfaces on the sealing surface, burrs or mold abnormalities that lead to abnormal sealing function failure of the product. Therefore, it is necessary to provide an efficient O-ring double seal. Utility Model Content
