PTFE wear rings

 

PTFE Wear rings 

 

 

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.

Styles	Uncut	Angle cut	Butt cut	Step cut
Direction	—	Left/right	—	—
Characteristics	Primarily used in small diameter pistons and piston rods.	Basic design of the reciprocating motion can effectively increase the load bearing stress at the gap.	It can be used for guiding in the form of rotary motion and easy to install.	It can guide the piston and reduce the pressure on the piston seal.
