Hydraulic Rod Seals RS-PU Type

The RS-PU type piston rod seal consists of a PU piston rod seal ring and an O-ring, used to seal the piston rod and piston of a hydraulic cylinder. The use of specially modified PU material can provide excellent low friction, wear resistance, pressure resistance, high temperature resistance and chemical corrosion resistance. The use of O-rings of different materials ensures a wide operating temperature range. Due to the special shape design, it has good oil film return characteristics. The RS-PU type is especially suitable for control cylinders, servo systems, machine tools, fast-response cylinders and construction machinery.

Applications:
Working pressure: ≤35MPa
Working temperature: -30℃～+180℃ (depending on the O-ring material)
Reciprocating speed: ≤4m/s
Media:
General petroleum-based hydraulic oil, water-glycol hydraulic oil, oil-water emulsion hydraulic oil.

Installation:
Rod diameter below 30mm requires open grooves to avoid damage to the sealing edge, measures should be taken to avoid sharp edges during installation.

Material:
Modified PU, high-performance NBR or FPM with different hardness, the standard type is high-performance NBR with hardness 70 degrees.
