Bronze-Filled PTFE Guide Strip — high wear resistance and low friction for hydraulic and pneumatic cylinders
Why Buyers Choose Bronze-Filled PTFE Guide Strip
Excellent Wear Resistance
The bronze filler significantly improves the abrasion resistance of PTFE, providing long service life even under high-load reciprocating conditions in hydraulic and pneumatic cylinders.
Low Friction Coefficient
PTFE provides an inherently low coefficient of friction, reducing energy loss, heat generation, and wear on the mating surface during piston and rod movement.
High Load-Bearing Capacity
Bronze-filled PTFE has higher compressive strength than pure PTFE, enabling it to withstand heavy radial loads in hydraulic cylinder rod and piston guidance.
Dry-Running Capability
Suitable for dry-running and boundary-lubricated conditions, making it reliable in applications where traditional oil lubrication is not available.
Chemical & Corrosion Resistance
Inherits PTFE's outstanding resistance to chemicals and corrosion, suitable for aggressive hydraulic fluids and harsh operating environments.
Wide Temperature Range
Operates continuously from -60°C to +150°C, covering both low-temperature outdoor hydraulic equipment and high-temperature industrial presses.
Vibration Absorption
Bronze-filled PTFE has excellent vibration absorption characteristics, reducing noise and improving stability in high-speed rod movement.
Embeddability for Particles
Foreign particles are embedded into the guide wear ring surface, preventing particle-induced damage to the cylinder bore and seals.

What is a Bronze-Filled PTFE Guide Strip?
A Bronze-Filled PTFE Guide Strip is a wear strip made from PTFE compounded with 30-50% bronze powder. It is used in hydraulic and pneumatic cylinders to guide the piston and rod, preventing metal-to-metal contact, reducing wear, and extending cylinder service life.
What is the temperature range of Bronze-Filled PTFE Guide Strip?
The working temperature range is -60°C to +150°C. This wide range covers both low-temperature outdoor hydraulic equipment and high-temperature industrial press applications.
Why use bronze filler in PTFE guide strips?
Bronze powder increases load-bearing capacity, thermal conductivity, wear resistance, and compressive strength. Bronze-filled PTFE performs better than pure PTFE in high-pressure hydraulic applications where higher load capacity and creep resistance are needed.
Which mating surfaces are compatible with Bronze-Filled PTFE Guide Strip?
Compatible with steel hard chrome, steel hardened, stainless steel, and hard anodised aluminium mating surfaces. Not recommended for soft mating surfaces such as untreated aluminium or soft bronze.
What is the maximum surface speed of Bronze-Filled PTFE Guide Strip?
The maximum surface speed is 15.0 m/s. Actual service speed may need to be reduced depending on load, temperature, lubrication, and mating surface condition.
Can Bronze-Filled PTFE Guide Strip be used in dry-running conditions?
Yes. Bronze-Filled PTFE Guide Strip has good dry-running capability due to the low friction of PTFE. For extended dry-running applications, contact our engineers for specific recommendations.
What information is needed for a quotation?
Please provide strip dimensions (length, width, thickness), quantity, application (hydraulic or pneumatic), operating temperature and pressure, mating surface material, and any drawing or sample. Custom sizes are produced to drawing.
