Piston Seal 140x117x16 PDH
Product Code:: PDH-128
PDH/A103 TYPE PISTON SEAL
Piston seal is design for double effect
cylinder where the pressure and working conditions
are heavy.
It is composed by three elements:
• static Part that has energizing function
• central Dynamic part has axial sealing function
• lateral antiextrusion Ring allow a greater radial
clearance between piston and bore cylinder.
Cylinders used on earth moving machines, lifting
machines and presses.
Technical data

Speed: <1.5 m/s
Temperature: da -35°C a + 150°
Fluids: mineral-based fluid and oil.
Material
• static energizing ring in NBR 80 Shore A
• dynamic seal in PTFE
• anti-extrusion Ring in thermoplastic material
(POM or PA).
Assembling
The assembling can be on monoblock or two-parts
piston.
Assembling sequence:
• NBR element
• PTFE element
• anti-extrusion ring.
Eliminate sharp edges and burrs to avoid damaging
the seal during assembly.
