CH19 is a four-piece double-acting heavy-duty compact seal which consists of one PTFE bronze profile ring, one elastomeric nitrile rubber pre-load sealing element and two thermoplastic back-up rings.
PROFILE
PRODUCT ADVANTAGES
• High sliding speed
• Low friction, free of stick-slip
• Simple groove design
• Long service life
• Very good sealing performance even with pressure peaks
• High resistance to abrasion
• Increased clearance possible
APPLICATION
Mining equipment, construction machinery and earth moving equipment.
INSTALLATION
The elastomeric ring should be assembled into the one-piece piston first, and then the special-mixture PTFE ring should be assembled with a special assembly tool. Lastly the split back-up rings should be installed. The required insertion chamfers on the piston and cylinder bore should be deburred and rounded. 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 special applications that require high temperatures, the piston seal is manufactured with an FKM pre-load component, pure PTFE back-up rings and special-mixture PTFE profile ring. Due to the design, CH19 can be used up to shock pressures of 600 bar safely.
