High-Performance Composite Bearings: PEEK and PTFE coated metal-polymer hydrodynamic composite bearings

Maximize the reliability and service intervals of your equipment with our precision-engineered composite bearings. In demanding environments where continuous lubrication is difficult or temperatures fluctuate significantly, standard polymer or bronze bearings often suffer from accelerated wear or thermal degradation. Our series solves this by integrating a high-strength PEEK/PTFE lining with a robust steel backing, providing a dimensionally stable, low-friction interface designed to thrive under marginal lubrication.

Why Choose Bearings?

The primary purpose of combining PEEK, PTFE, and high-grade steel is to achieve Extreme Thermal Stability and Maintenance-Free Durability. Through a multi-layer sintering process, our bearings offer:

• Exceptional Thermal Range: Engineered to maintain structural integrity and performance across a vast temperature spectrum, from -150°C to +250°C.
• High PV Capability: Optimized for high-load and high-speed applications, delivering superior performance even when only minute quantities of lubricant are present.
• Zero Water Absorption & Chemical Inertness: Unlike nylon-based alternatives, the PEEK/PTFE matrix does not swell in humid environments and resists a wide array of industrial chemicals.

Multi-Layer Material Structure

Our bearings utilize a sophisticated four-layer architecture to balance strength with friction reduction:

1. PEEK + PTFE (0.30–0.50mm): The primary sliding surface featuring circular indents (grease pockets) for optimized wear resistance and ultra-low friction.
2. Sintered Bronze Powder (0.20–0.35mm): Acts as a thermal conductor to dissipate heat and provides a porous "interlock" for the polymer lining.
3. High-Strength Steel Backing: Provides the essential mechanical rigidity and high static/dynamic load-carrying capacity.
4. Copper/Tin Plating (0.002mm): Ensures superior corrosion resistance for the external shell in harsh operating conditions.

Strategic Applications

 bearings are the backbone of high-precision hydraulic and mechanical systems, including:

• Fluid Power & Hydraulics: High-pressure gear pumps, piston pumps, and gear motors.
• Automotive Systems: ABS braking systems and steering assemblies.
• Agriculture & Construction: Heavy-duty pivot points in tractors and earthmoving machinery.
• Industrial Manufacturing: High-cycle machine tools and automated sliding guides.
