Description
SPN is a two-way piston rod seal consisting of a PTFE composite seal ring and a O-ring.
SPN seals are especially suitable for controlling cylinder servo systems, machine tools, cylinder quick response and construction equipment, and two-way piston rod cylinders. This filler has low frictional resistance, which eliminates stick-slip and ensures high wear resistance. When the service range of stress is used, wide and fast sliding speed.
SPN sealing ring has high chemical resistance and corrosion resistance. O-rings and sealing rings of different materials can be used. SPN sealing ring can be applied to almost all media. Since the special shape of the sealing structure has good film properties, it can be returned to the oil.
