RP-75


Description

The RP-75 is a single acting piston - rod seal and is designed with symmetrical lips in order to be used both for rod and piston applications. The standard material of the RP-75 is Polyurethane 94 shore.


Product advantages

  • superior static and dynamic sealing effect
  • wide range of dimensions
  • easy assembly into closed grooves
  • simple groove design
  • economical sealing solution


Applications

  • construction machinery
  • injection moulding machines
  • fork-lift trucks
  • agricultural machinery
  • loading platforms
  • standard cylinders

Drawing RP-75

Installation

Easily assembled into closed grooves according to the minimum diameter values that are given in the below table. Open grooves or special assembly tools should be used for the values that are outside this table. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the seal must be oiled with system oil.


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 ≤3.2 μm ≤16 μm

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

Sealing gap

t>5  0,35 0,25 0,20


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.
