Rod and piston wear rings guide pistons and piston rods in a hydraulic cylinder, preventing metal to metal contact and minimizing transverse forces, reducing friction and optimizing the performance of piston and rod seals.
Kintowe rod and piston wear rings consists of fine cotton fabric bound with thermosetting phenolic resin under certain temperature and pressure. Compared to metal guides, our composite wear rings provide the following advantages:
Easy to install
Tight tolerances
Reduce vibration
Good wear resistance
Low thermal expansion
Able to withstand high cycling speeds
