PTFE Bronze Wear Rings
PTFE bronze wear rings are high-performance guiding elements used in hydraulic cylinders to prevent metal-to-metal contact between the piston or rod and the cylinder wall. Manufactured from PTFE filled with 40% bronze, these wear rings offer superior wear resistance, low friction, and excellent chemical compatibility, making them ideal for high-speed, high-load, and aggressive media environments.

Material Comparison
Compared with other wear ring materials like phenolic resin or polyester fabric composites, PTFE bronze wear rings provide significantly lower friction and improved thermal performance, particularly in environments where traditional materials degrade more quickly.
For applications requiring higher load capacity and temperature resistance, consider our phenolic wear rings.
How to Choose the Right Wear Ring
Confirm cylinder type: piston or rod side
Measure housing groove width and depth accurately
Check application parameters: load, speed, media, and temperature
Ensure compatibility with other seals, such as rod seals or piston seals
FAQ
Q: Why choose PTFE with bronze filler?
A: Bronze-filled PTFE offers higher thermal conductivity, better dimensional stability, and greater wear resistance than virgin PTFE.
Q: Can I order custom sizes?
A: Yes. We provide custom-made PTFE bronze wear rings based on your specific groove dimensions and application needs.
