Product Description

Chunhuan’s reinforced PTFE (Polytetrafluoroethylene) bushings are engineered to outperform traditional metal bushings and bearings. By integrating advanced filler materials like fiberglass, carbon, or bronze into a premium PTFE matrix, we deliver a component that eliminates the need for external lubrication, reduces maintenance downtime, and provides exceptional performance in the most demanding environments. These bushings are the ideal solution for applications requiring extreme chemical resistance, a wide operating temperature range, and low friction.

Key Features & Advantages

  • Maintenance-Free Self-Lubrication: Ultra-low friction coefficient (0.02 – 0.1) eliminates grease and oil, preventing contamination and reducing lifetime costs.
  • Exceptional Temperature Resistance: Performs reliably in temperatures from -200°C to +260°C, with short-term peaks up to 300°C.
  • Superior Chemical Resistance: Withstands harsh acids, alkalis, and solvents, offering a service life 3-5x longer than metal alternatives.
  • Anti-Stick & Non-Galling: Ensures smooth operation without seizing, even in dusty or humid conditions.
  • Lightweight & Noise Reduction: 30% lighter than metal parts and reduces operational noise by over 15dB.
