Hydraulic machine UN piston rod seal is used for the excavator to be installed on the piston. The main function is to seal the gap between the piston and the cylinder to prevent leakage of hydraulic oil. The piston seal is the main seal in the hydraulic cylinder. It is one of the most important seals for the hydraulic cylinder to withstand the pressure. The main requirements for the piston seal are good sealing effect, good pressure retention effect in static state, strong pressure bearing capacity during exercise, anti-extrusion, small friction coefficient and long service life....
Send InquiryHydraulic seals are generally relatively soft, non-metallic rings captured in groove or fixed in a combination of rings, forming a seal assembly, to block or separate fluid in reciprocating motion applications. Hydraulic seals are vital in machinery. Their use is critical in providing a way for fluid power to be converted to linear motion.
Hydraulic seals can be made from a variety of materials such as polyurethane, rubber or PTFE. The type of material is determined by the specific operating conditions or limits due to fluid type, pressure, fluid chemical compatibility or temperature.
A static hydraulic seal is located in a groove and sees no movement - only sealing within its confined space, acting like gasket.
A type of dynamic hydraulic seal called a rod seal is exposed to movement on its inner diameter along the shaft or rod of a hydraulic cylinder. A type of dynamic hydraulic seal called a piston seal is exposed to movement on its outer diameter along the tube or bore of a hydraulic cylinder.
