PS-65


Description

The PS-65 is a two piece single acting piston seal which consists of asymmetrical profile with pressure relieving grooves and a thermoplastic back-up ring.

Material: PU with a POM back-up ring


Product advantages

  • superior static and dynamic sealing effect
  • improved sealing gap thanks to the active back-up ring
  • relief grooves against dynamic pressure
  • easy assembly into the closed groove
  • simple groove design
  • high wear resistant


Applications

Heavy duty cylinders, crap cutters and hydraulic jacks


Operating conditiones

Media Mineral oils (DIN 51524) HFA and HFB HFC
Temperature (min.) °C -30 +5 -30
Temperature (max.) °C +100 +50 +40
Pressure Bar ≤400 ≤400 ≤400
Speed m/sec  ≤0,5  ≤0,5  ≤0,5


Surface roughness

Surface roughness  Ra Rmax
Sliding Surface ØD-Ød ≤0.4 μm ≤3.2 μm
Groove Base ØDb-Ødp ≤1.6 μm ≤10 μm
Groove Flanks B ≤4.0 μm ≤16 μm

Note: It is recommended to have 50% to 90% of the working surface value.


Drawing PS-17


Installation

Easily assembled into one piece piston. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation all individual parts of the seal must be oiled with system oil.


Permissible sealing gap

pressure (bar) 100 150 250 400
Smax (mm.) 1,00 0,80 0,70 0,60

Note: The largest sealing gap value occurring on the non-pressurized side of the seal is vital for the function and in this respect it is quite important to use the S value lower than the above indicated numbers.


We can also produce this piston seal on request in the materials below. This is our type DK102-R.
