705-55-24130 Komatsu WA320-8 High Quality Wheel Loader Hydraulic Gear Pump Excavator Seal Kit
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.
