Premium PEEK & PTFE Coated Washers: High-Performance Marginally Lubricated Solutions

Elevate your machinery’s endurance with our PEEK and PTFE Coated Thrust Washers. In high-temperature or high-load environments, standard self-lubricating washers often suffer from accelerated wear or material degradation. Our series addresses these challenges through a specialized composite structure and a unique circular indent surface pattern, engineered to retain grease and provide superior performance during boundary lubrication.

Why Choose Thrust Washers?

The primary advantage of the series is its High PV Capability and Thermal Resilience. By integrating advanced PEEK polymers with a robust steel foundation, these washers offer:

• Exceptional Temperature Range: Operates reliably in extreme conditions ranging from -150°C to +250°C.
• Marginal Lubrication Excellence: Features circular indents on the sliding surface designed to be filled with grease upon assembly, ensuring long-term operation with minimal maintenance.
• High Load & Speed Capacity: Engineered for high static and dynamic loads while maintaining a low coefficient of friction even under light-duty, low-speed dry running.

Advanced Multi-Layer Structural Integrity

The material is a four-layer composite designed for maximum mechanical strength and chemical resistance:

1. PEEK + PTFE Overlay (0.30~0.50mm): A thick, high-wear-resistance layer with surface indents for grease retention.
2. Sintered Bronze Layer (0.20~0.35mm): Provides maximum thermal conductivity and serves as a mechanical anchor for the PEEK/PTFE mixture.
3. High-Strength Steel Backing: The core foundation that provides high load-carrying capacity and structural rigidity.
4. Copper/Tin Plating (0.002mm): A specialized protective coating that provides enhanced corrosion resistance for the backing.

Typical Applications

SB-HIEX washers are engineered for precision motion in demanding industrial components:

• Automotive Systems: Essential for ABS systems, piston pumps, and gear motors.
• Hydraulic Components: High-performance gear pumps and fluid power systems.
• Heavy Machinery: Agricultural equipment and industrial machine tools.
• Versatile Motion: Optimized for rotating, oscillating, reciprocating, and sliding movements.
