In the world of high-performance propulsion, internal components must do more than just "fit"—they must excel. When an automatic transmission faces the relentless torque and thermal cycling of industrial, commercial, or vocational applications, standard hardware isn't enough.

Mithson Carbon-Filled PEEK (Polyether Ether Ketone) thrust washers represent the pinnacle of polymer engineering. Specifically designed to replace traditional metal and glass-filled plastics, these washers provide the durability of a bearing with the versatility of a high-performance thermoplastic.

Why Choose Carbon-Filled PEEK?

Standard "virgin" PEEK is a strong material, but Carbon-Reinforced grade is in a class of its own. By integrating high-modulus carbon fibers, we have developed a thrust washer that manages extreme axial loads while maintaining an incredibly low coefficient of friction.

1. Advanced Thermal Management

Heavy-duty transmissions operate in high-heat environments where lubricants are pushed to their limits. The integrated carbon fibers significantly increase thermal conductivity, efficiently dissipating heat away from the friction interface. This prevents localized "hot spots" and ensures the material maintains its structural integrity at continuous temperatures up to 250°C (482°F).

2. Exceptional PV (Pressure-Velocity) Limits

In demanding applications, the "Pressure x Velocity" (PV) limit is the difference between long-term reliability and premature failure. Our Carbon-Filled PEEK handles nearly double the PV load of glass-filled alternatives, making it the ideal choice for:

• Planetary Gear Carriers

• Output Shaft Thrust Positions

• High-Pressure Pump Wear Plates

3. Self-Lubricating Reliability

The carbon fiber reinforcement acts as a solid lubricant. During "boundary lubrication" events—such as cold starts or high-torque shifts where the oil film may be thin—our washers provide a self-lubricating surface that prevents metal-to-metal galling and reduces parasitic power loss.
