carbon filled ptfe piston shaft sealing rings bronze filled PTFE hydraulic cylinder wear ring seals

The filled PTFE wear ring is suitable for guiding the hydraulic cylinder, the piston and the piston rod in the cylinder, and functions as a support and guide.

They guide the rod or the piston and prevent metallic contact with the cylinder when radial forces act perpendicular to the direction of movement. The wear ring protects critical sealing lips from contamination effects. The compound used for these guides assures an exceptional low friction and high speed performance,a high compatibility with nearly all media due to the chemical resistance which exceeds that of all other thermoplastics and elastomer.

Advantages for hydraulic cylinder piston seals rings

- Avoid contact between metals

- High load resistance

- High speed allowed

- Low friction

- With wiping function

- Simple installation

- Can suppress mechanical vibration

Material for wear rings

Could be filled PTFE, such as carbon fibre filled ptfe, bronze filled ptfe etc.

And phenolic fabric etc.
