SSO is a single acting rod seal which consists of reinforced cotton fabric and nitrile rubber vulcanized together forming an integral sealing element.
PRODUCT ADVANTAGES
- Functions evenwith poor surfaces
- Reinforced cotton fabric base prevents the seal from extrusion
- Good sealing at low pressures
APPLICATION
Mobile hydraulics and Standard cylinders

| MEDIA | Mineral oils(DIN 51524) | HFA and HFB | HFC |
| TEMPERATURE | -30°C +105°C | +5°C +60°C | -30°C +60°C |
| PRESSURE | ≤250 Bar | ≤250 Bar | ≤250 Bar |

Note: The above data are maximum values and cannot be used at the same time.
| 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.
INSTALLATION
SSO is to be assembled into open grooves if rod diameter is less than 40 mm. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the sealing elements must be oiled with system oil.
NOTES The permissible sealing gap values of SSO rod seal is given in the below table.
| PERMISSIBLE SEALING GAP | |||
| Pressure (Bar) | Smax (mm) | ||
| 150 Bar | 250 Bar | ||
| 0.2 | 0.1 | ||
Note: The largest sealing gap value occuring 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.
