Piston Rod Seal PU-RS Hydraulic O Ring Seals

RS type piston rod seal is composed of PTFE piston rod seal ring and O-ring, which is used for piston rod and plunger seal of hydraulic cylinder. Due to the use of specially modified PTFE material, it can ensure excellent low friction, wear resistance, pressure resistance, high temperature resistance and chemical corrosion resistance. The use of O-rings of different materials guarantees a wide operating temperature range. Due to the special shape design, it has good oil film return characteristics. The RS type is especially suitable for controlling cylinders, servo systems, machine tools, quick response cylinders and construction machines. Application range: Working pressure: ≤40MPa Working temperature: -30℃～+180℃ (depending on O-ring material) Reciprocating speed: ≤4m/s medium: General-purpose petroleum-based hydraulic oil, water glycol hydraulic oil, oil-water emulsified hydraulic oil. Install: If the rod diameter is less than 30mm, an open gro…
