Hebei Hankai hydraulic motor seal kit

Wiper oil seals often feature a unique design that includes a lip that contacts the shaft or surface it is sealing against. This lip creates a dynamic seal that adapts to the movement of the shaft, maintaining a tight enclosure even as the equipment operates. The design often includes an additional wiper or dust lip, which helps remove contaminants that come into contact with the seal, further enhancing its protective capabilities.

In 1839, American chemist Charles Goodyear made vulcanized rubber by accident and applied for a patent for it. A few years later, an Anglo-American businessman, Hiram Hutchinson, purchased the patent and in 1853 opened a rubber products company in France called l'Aigle (translated as to the Eagle in honor of the United States), where he began making Wellington boots from vulcanized rubber.
