RP-30


Description

The RP-30 is a single acting piston seal which consists of reinforced cotton fabric and nitrile rubber vulcanized together forming an integral sealing element.


Product advantages

  • functions even with poor surfaces
  • reinforced cotton fabric base prevents the seal from extrusion
  • both rod and piston application
  • good sealing at low pressures


Applications

Low to medium duty hydraulic cylinders, mobile hydraulics and presses.


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 ≤250 ≤250 ≤250
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 RP-30

d (h9)/dp (f8)

Db (H11)/D(H9)

B (-0/+0.2)


Installation

The RP-30 is to be assembled into open grooves. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the sealing element must be oiled with system oil.


permissible sealing gap

pressure (bar) 150 250
Smax (mm.) 0,20 0,10

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