Configuration information
Shaft rod seal. Common ones include V-rings, U-rings, and combination sealing rings. U-shaped ring: This type of sealing ring can be used alone, and can be used alone when the system working pressure does not exceed 20MPa. If used alone beyond 20MPa, a retaining ring is generally required. V-shaped ring: Its usage is similar to that of V-shaped rings used for piston, requiring the use of open grooves, and the guiding components are generally made of copper sleeves.
Dust ring. Common types include double acting dust rings and single acting dust rings.
Piston Seal. Common types include V-rings, U-rings, SPGO rings, and combination sealing rings, which include V-rings for piston, SPGO rings for piston, U-rings for piston, and combination sealing rings. V-shaped rings are generally used for heavy-duty hydraulic cylinders, with reliable sealing. They generally need to be installed in pairs back-to-back with open grooves. The guiding element of this type of sealing ring is usually copper sleeve. Both open and closed grooves can be used, and many of their guiding components use guiding belts. This sealing ring comes with a guiding element, and after using this sealing ring, no other guiding elements can be added.
Guide ring. Such as phenolic resin cloth guide sleeve, PTFE guide sleeve, POM guide ring, etc.
O-ring. Generally used as a static seal, if the working pressure exceeds 20MPa, it is generally necessary to add a polytetrafluoroethylene (PTFE) material retaining ring.
