Seals For Piston Assemblies

- Nov 08, 2017 -

Piston device is mainly used to prevent the leakage of hydraulic oil, good seal is the hydraulic cylinder transmission power, the normal movement of the guarantee, according to the two need to seal the coupling between the surface there is no relative movement, can be divided into dynamic seals and static seals two categories. The basic requirement of the design or selection of sealing device is a good sealing performance, and with the increase of pressure can automatically improve the sealing, in addition, friction resistance to small, oil resistance, corrosion resistance, wear resistance, long life, simple manufacturing, easy disassembly.
