Material Description
1. Nitrile Rubber (NBR) Suitability
Nitrile rubber is the most common base material for construction machinery seals due to its:
• Excellent Oil Resistance: Resistant to hydraulic oil, gear oil, and other media erosion.
• High Wear Resistance: Broad hardness range (Shore A 60-90), suitable for high-load working conditions.
• Anti-Aging Performance: Maintains elasticity in temperatures ranging from -40°C to 100°C, meeting the operational temperature requirements of excavator axles.
Typical applications: NBR oil seals are commonly used in general hydraulic systems and gearbox sealing.
2. Fluororubber (FKM)
Fluororubber may be used for high-end products or extreme working conditions (e.g., high temperatures, chemical corrosion):
• High-Temperature Resistance: Operates at temperatures exceeding 200°C, suitable for high-heat environments like mining machinery.
• Chemical Stability: Superior resistance to acids, alkalis, and solvents compared to NBR, extending seal lifespan.
Limitations: Higher cost, typically used in specialized scenarios (e.g., deep-sea equipment, aerospace).
3. Optimized Composite Materials
Some high-end oil seals use NBR with PTFE coating or metal skeleton reinforcement:
• PTFE Coating: Reduces friction coefficient, minimizes shaft wear, and enhances sealing performance.
• Metal Skeleton Reinforcement: Enhances structural stability and prevents deformation, ideal for high-pressure environments.
Translation Notes:
• Technical terms and performance metrics are retained for accuracy.
• Bullet points and section headers maintain readability, aligning with industrial documentation standards.
• Flow is optimized to highlight material advantages, limitations, and real-world applications for buyers.
