60% Bronze Filled PTFE Rod – KXT B980
Kaxite Sealing, a professional China PTFE rod manufacturer, presents the KXT B980 60% Bronze Filled PTFE Rod – a high-performance engineering material that combines the exceptional chemical resistance and low friction of PTFE with the superior wear resistance, thermal conductivity, and creep resistance of bronze filler. This dark brown composite is the most common metal-filled PTFE, designed for demanding bearing, seal, and wear pad applications where high mechanical loads and elevated speeds are encountered.
Why KXT B980? With 60% bronze powder uniformly dispersed throughout the PTFE matrix, this material offers outstanding wear resistance, excellent thermal conductivity to dissipate heat, and low friction for smooth operation. It is ideal for use in hydraulic systems, linear bearings, slides, guideways, piston rings, and bearing rings where shafts are not hardened. The bronze filler provides the strength and thermal management needed for high-speed rubbing contact points.
As a leading PTFE rod supplier in China, Kaxite offers the KXT B980 in a wide range of diameters and lengths, with custom sizes available upon request. This product is machined easily and is a popular choice for engineers seeking a durable, self-lubricating material for heavy-duty applications. Request a free sample or get a wholesale quote today.

Why KXT B980 60% Bronze Filled PTFE Rod?
- Excellent Wear Resistance – Bronze filler dramatically reduces wear in high-friction applications, extending component life.
- Superior Thermal Conductivity – Effectively dissipates heat generated at rubbing contact points, preventing overheating.
- Low Friction – PTFE matrix provides a low coefficient of friction, ensuring smooth operation without stick-slip.
- Creep Resistance – Bronze filler reduces cold flow (creep) under load, maintaining dimensional stability.
- Easy Machinability – Can be turned, milled, drilled, and tapped to precise dimensions with standard tooling.
- Versatile Application – Ideal for bearings, slides, guideways, piston rings, and hydraulic sealing components.
Key Features & Performance Benefits
Superior Wear Resistance – The 60% bronze filler significantly enhances resistance to abrasion and galling, making it suitable for high-load, high-speed applications.
High Thermal Conductivity – Bronze particles conduct heat away from the contact surface, reducing thermal expansion and maintaining tight tolerances.
Low Coefficient of Friction – PTFE provides inherent lubricity, minimizing friction and wear on mating surfaces, even in dry-running conditions.
Excellent Creep Resistance – The bronze filler reduces cold flow, allowing the material to maintain its shape and clearance under sustained loads.
Good Tensile Strength – The bronze filler improves mechanical strength compared to unfilled PTFE, providing better load-bearing capacity.
Easy to Machine – Can be machined to close tolerances with conventional metalworking equipment, enabling cost-effective production of custom parts.
Typical Applications
Linear Bearings & Slides High-speed, low-friction bearings for machine tools, automation equipment, and precision positioning systems.
Hydraulic Systems Piston rings, wear rings, and guide rings for hydraulic cylinders, pumps, and valves requiring wear resistance and low friction.
Bushings & Wear Pads Flanged bearings, thrust washers, and wear plates for heavy-duty industrial equipment, construction machinery, and mining applications.
Guideways & Ways Slideways for machine tool tables, carriage guides, and linear motion systems requiring smooth, low-friction movement.
Sealing Components Extrusion rings, back-up rings, and custom seals for hydraulic and pneumatic applications.
General Mechanical Parts Gears, cams, rollers, and other sliding or rotating components where wear and heat dissipation are critical.
Technical Highlights – KXT B980 Bronze Filled PTFE
The performance of bronze-filled PTFE is highly dependent on the filler content and dispersion quality. Kaxite ensures uniform distribution of 60% bronze powder throughout the PTFE matrix for consistent properties.

Frequently Asked Questions About Bronze Filled PTFE Rod
- Q: What is the advantage of 60% bronze filled PTFE over unfilled PTFE?
- A: Bronze filling significantly improves wear resistance, creep resistance, and thermal conductivity while maintaining the low friction of PTFE. It is much more durable in high-load, high-speed applications compared to unfilled PTFE.
- Q: Is this material suitable for chemical service?
- A: Bronze filled PTFE has poor resistance to acids and alkalis – the bronze will corrode. It is not recommended for chemical environments. For such applications, consider glass or carbon filled PTFE.
- Q: What is the maximum operating temperature?
- A: The PTFE matrix allows continuous service up to +260°C. However, the bronze filler can tolerate higher temperatures, but the PTFE will soften above 260°C, so the practical limit is around 260°C for long-term use.
- Q: Can this material be machined to tight tolerances?
- A: Yes, bronze filled PTFE machines very well. With proper tooling and techniques, tolerances of ±0.05 mm or better can be achieved.
- Q: What is the minimum order quantity (MOQ)?
- A: Our standard MOQ is 10 kg per diameter, but we are flexible for sample orders (1–2 kg) to allow you to test the material. For custom diameters or special filler grades, MOQ may vary – contact us for a tailored quote.
