PS-33


Description

The PS-33 is a three-piece single acting piston seal set which consists of reinforced one cotton fabric and nitrile rubber vulcanized together, one L shaped thermoplastic guide back-up ring and a retaining ring.


Product advantages

  • functions even with poor surfaces
  • limited space thanks to the open housing in one-piece piston
  • reinforced cotton fabric base prevents the seal from extrusion
  • good sealing at low pressures


Materials

  • NBR 80 shore A
  • Cotton fabric NBR
  • POM back-up ring


Applications

Mining equipment, after market, mobile hydraulics, presses and standard cylinders.


Operating conditions

Media Mineral oils (DIN 51524) HFA and HFB HFC
Temperature (min.) °C -30 +5 -30
Temperature (max.) °C +105 +60 +60
Pressure Bar ≤500 ≤500 ≤500
Speed m/sec  ≤0,5  ≤0,5  ≤0,5

Note: The above data are maximum values and cannot be used at the same time.


Surface roughness

Surface roughness  Ra Rmax
Sliding Surface ØD-Ød ≤0.4 μm ≤3.2 μm
Groove Base ØDb-Ødp ≤1.8 μm ≤6.3 μm
Groove Flanks B ≤3.2 μm ≤16 μm

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


Drawing PS-33


Installation

The PS-33 is easily assembled into one-piece piston by hand. Open groove design gives an advantage for easy machining and reducing the machining costs. It is very important that the installation 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.
