RS-74
Description
The RS-74 is a two piece single acting rod seal which consists of one elastomeric sealing element specially designed with additional sealing lip and one thermoplastic back-up ring.
Materials: PU 94 shore A with a POM back-up ring
Product advantages
- high wear resistant
- superior sealing effect
- secondary sealing lip provides extra protection against the ingress of dirt particles
- improved sealing gap due to the active back-up ring
- simple groove design
Applications
- construction machinery
- injection moulding machines
- fork-lift trucks
- agricultural machinery
- standard cylinders
Operating conditions
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 |
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 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.
Minimum diameter values for closed type of grooves
(D-d)/2 (mm.) | 4 | 5 | 6 | 7,5 | 10 | 12,5 | 15 |
dmin (mm.) | 25 | 30 | 40 | 50 | 80 | 100 | 105 |
Sealing gap
permissible sealing gap | |||
Pressure (Bar) | 150 | 250 | 400 |
Smax (mm) | 1,0 | 0,8 | 0,6 |
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.
