Product Introduction
PTFE Bearing
Definition
A PTFE bearing is a specialized sliding bearing manufactured with polytetrafluoroethylene (PTFE) as its core material. Its unique properties establish critical industrial applications under extreme conditions.
Core Characteristics
- Ultra-Low Friction Coefficient (0.04–0.05):
- Self-lubricating design reduces energy consumption and eliminates maintenance needs.
- Extreme Temperature Resistance:
- Operational range: -200°C to 260°C (short-term tolerance up to 300°C).
- Superior Chemical Inertness:
- Resists corrosion by strong acids (e.g., aqua regia, hydrofluoric acid), strong alkalis, and organic solvents; compatible with pH 0–14 media.
- Wear & Aging Resistance:
- No performance degradation over long-term use; resistant to UV radiation and ozone corrosion.
Key Application Fields
- Chemical & Energy:
- Reactor agitator shafts, acid pump valves (hydrofluoric acid resistance).
- Advanced Manufacturing:
- Aerospace hydraulic systems, automotive steering pump bearings (high/low-temperature cyclic endurance).
- Medical & Food:
- Aseptic filling equipment, pharmaceutical machinery (FDA-certified, non-toxic, pollution-free).
- Semiconductor Industry:
- Ultra-pure media delivery pipelines (prevents metal ion contamination).
Performance Advantages
- Zero external lubrication: Avoids grease contamination (ideal for cleanrooms).
- Reduces noise/vibration and extends equipment lifespan.
- Pressure resistance up to 10.5 MPa via metal/fiber reinforcement.
Note: PTFE bearings deliver "zero contamination, maintenance-free operation, and wide temperature adaptability," making them ideal solutions for demanding industrial environments.
