CH704 is a two-piece single-acting rod seal which consists of one special mixture PTFE profile ring and an NBR elastomer ring as energizing element.

PROFILE

 
PRODUCT ADVANTAGES
• Low friction, free of stick-slip
• Long service life
• High sliding speed
• Wide range of temperature and chemicals depending on the energizing material
• Minimum static and dynamic friction coefficient for minimum energy loss
• Simple groove design and low axial housing heights

APPLICATION
Steel industry, injection moulding machines, presses, large diameter cylinders

INSTALLATION
We recommend using assembly tools. (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.

NOTES
For applications where HFA, HFB and HFC are used, special filled PTFE materials are recommended. Resistance in low temperature and high temperature applications can be improved by alternate elastomer compounds.
