1. Product Advantages
- Superior Durability: Carbon fiber reinforcement enhances PTFE’s mechanical strength by 30%, resisting wear and deformation under continuous rotational motion.
- Extreme Environment Adaptability: Withstands temperatures from -200°C to 260°C (-328°F to 500°F) and is inert to acids, alkalis, and most organic solvents.
- Leak-Proof Performance: Precision-molded structure ensures tight sealing, reducing leakage risks to near-zero in industrial applications.
- Low Maintenance: Self-lubricating PTFE material minimizes friction, extending service life and cutting down on replacement frequency.
2. Working Principle
The GNS rotary seal operates by forming a dynamic barrier between rotating and stationary components. Its carbon fiber-reinforced PTFE matrix maintains dimensional stability under rotational stress, while the PTFE’s inherent lubricity reduces friction between the seal and shaft. The seal’s lip design conforms to the shaft surface, creating a pressure-tight seal that prevents fluid or gas leakage. The carbon fiber additive enhances heat dissipation, ensuring consistent performance even in high-temperature or high-speed operating conditions.
3. Product Details
- Material Composition: 90% premium PTFE + 10% high-modulus carbon fiber (uniformly distributed for optimal reinforcement).
- Dimensions: Customizable to fit shafts ranging from 10mm to 200mm (0.39” to 7.87”); standard tolerance: ±0.02mm.
- Surface Finish: Polished to Ra ≤ 0.2μm for reduced friction and improved sealing contact.
- Design Feature: Integral anti-extrusion ring prevents seal deformation under high pressure (up to 10MPa/1450psi).
4. Application Scope
Ideal for rotating shaft sealing in industries including:
- Manufacturing (pumps, motors, gearboxes)
- Chemical processing (reactors, pipelines, valves)
- Automotive (engine components, transmission systems)
- Aerospace (hydraulic systems, rotating machinery)
- Food & Beverage (sanitary pumps, mixing equipment)
- Renewable Energy (wind turbine generators, solar thermal systems)
5. FAQ
Q1: What is the maximum rotational speed this seal can handle?
A1: It supports speeds up to 5m/s (16.4ft/s) for standard sizes; custom high-speed versions (up to 8m/s) are available upon request.
Q2: Can it be used with water-based fluids?
A2: Yes—PTFE’s chemical inertness makes it compatible with water, oil, grease, and most liquid/gas media.
Q3: How often should the seal be replaced?
A3: Typical service life is 2,000–5,000 operating hours (varies by application); regular inspection is recommended for high-stress environments.
Q4: Is custom sizing available?
A4: Absolutely—Forever Seals offers tailored dimensions, materials, and designs to meet specific customer requirements.
