With the application of hydraulic cylinder, the seal ring has played a vital role in all walks of life, and the sealing industry is also actively developing in order to better adapt to the requirements of modern industry for sealing, after so many years of development, the cylinder seal has also had a relatively stable supporting: Seal ring for rod, seal ring for hole, dust ring, guide belt and foundation seal (O-ring, etc.).
Common seal rings for rod include: shaft seal, shaft grid ring, shaft Y ring, shaft U ring, V ring, tie rod seal, etc
The hole sealing ring basically corresponds to the rod sealing ring, and also includes some piston special sealing rings: TPM/DAS combination sealing ring, two-way piston seal, heavy duty piston seal, etc.
Dustproof ring series: single lip dustproof, double lip dustproof, saddle-shaped dustproof ring, metal skeleton dustproof ring and tetrafluoride dustproof.
Guide belts are commonly made of two materials: phenolic cloth and PTFE+ bronze powder.
Of course, some static seals will be used in the cylinder, the most common is the O-ring, which can be provided according to the specific working conditions of the cylinder: nitrile rubber, fluorine rubber and so on.
