K78 Hydraulic guiding elements
K78 piston-rod guide rings are composite guiding elements, produced from aramid fabric and phenolic resin which provides high load carrying capacity designed to be used in rod and piston applications in hydraulic systems. Compared to regular composite guide rings, K78 has a higher temperature resistance due to Aramid fabric.
Advantages
- Operating at high temperature
- The high form stability at operating temperature range
- Easy installation
- Wide range of dimensions
- Can be used in heavy and medium duty applications
Area of Application
- Iron and steel industry
- Mobile machinery
- Heavy duty cylinders
