K518X Hydraulic piston seals
K518X is a high-performance double acting compact piston seal that consists of one NBR profile ring, thermoplastic elastomer support rings, and glass-reinforced PA guide rings. Among similar double-acting piston seals, K518X comes forward with its TPE support rings with special geometry which enhances the extrusion resistance at variable pressures of mobile hydraulic applications and glass-reinforced PA guide rings that provides higher load bearing performance at higher temperatures.
Advantages
- Ultimate extrusion resistance due to special TPE back-up rings
- Better high temperature resistance due to PA guide rings
- Advanced performance at long stroke cylinders
Area of Application
- Agricultural machinery
- Construction machinery
- Mobile machinery
- Loading platforms
- Forklifts
