O-rings are the most widely used seals in hydraulic engineering and are used primarily for static and sliding seals. Advantages: 1 dynamic and static sealing, good sealing and long life. 2 small size, light weight and low cost. The sealing part has a simple structure, small occupied space, convenient loading and unloading, and a single ring can seal the two aspects. 3 adaptability to oil temperature and pressure. Disadvantages: When the dynamic seal is used, the starting friction resistance is large, about 3 to 4 times of the dynamic friction resistance. When the static seal is used, the O-ring seal is inserted into the seal groove and its cross section
