Guide Ring is a mechanical seal, also known as a guide ring. It is usually made of metal or plastic and used to support and position pistons or rods. Guide Ring has excellent wear resistance and corrosion resistance, which can effectively reduce leakage and friction, thereby extending equipment life. Guide Ring is widely used in the hydraulic, pneumatic, mechanical, and automotive industries as an important mechanical seal.
The classification of Guide Ring can be divided by material, structure, and purpose. According to material classification, Guide Rings are mainly divided into metal Guide Rings and plastic Guide Rings. Metal Guide Rings are usually made of metals such as copper, iron, and stainless steel, which have high strength, wear resistance, and high-temperature resistance; The plastic Guide Ring is usually made of polytetrafluoroethylene (PTFE), nylon, polyimide and other materials, with good corrosion resistance and low friction coefficient.
According to structural classification, Guide Rings are mainly divided into unidirectional Guide Rings and bidirectional Guide Rings. A unidirectional guide ring can only withstand pressure in one direction and is typically used in hydraulic and pneumatic systems; The bidirectional guide ring can withstand bidirectional pressure and is typically used in the mechanical and automotive industries.
According to usage classification, Guide Rings are mainly divided into piston Guide Rings and rod Guide Rings. The piston guide ring is usually used to support and position the piston, preventing friction and leakage between the piston and the cylinder liner; The rod guide ring is used to support and position the rod, preventing friction and leakage between the rod and the seal.
