We recommend using special assembly tool (See section; Hydraulic Sealing Elements General Installation Information). 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
For special applications that require high temperatures , rod seal is manufactured in FKM and PTFE material. .
|PERMISSIBLE SEALING GAP|
|B (mm)||Smax (mm)|
|X||150 Bar||250 Bar||400 Bar|
Note: All the above mentioned "S" values are maximum and it's vital to use lower values for system security.
|MATERIAL PTFE BRONZE + NBR 80SH|
|MEDIA||Mineral oils (DIN 51524)|
Note: The above data are maximum values and cannot be used at the same time. For HFA HFB HFC used applications , special filled PTFE materials are recommended. Resistance in low temperature and high temperature applications can be improved by alternate elastomer compounds.
|Sliding Surface ØD||≤0.2 μm||≤2.0μm|
|Groove Base Ød||≤1.6 μm||≤6.3μm|
|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.
