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.
