定义
A precision-engineered leather seal body designed specifically for hydraulic piston applications, providing effective fluid containment and pressure maintenance in hydraulic systems. This component serves as the structural foundation for sealing elements in leather hydraulic piston seals, ensuring proper alignment and compression against mating surfaces.
工作原理
The leather seal body functions by providing a stable, compressible structure that maintains consistent contact pressure between the sealing element and the piston/cylinder interface. It deforms under hydraulic pressure to create a tight seal while allowing controlled movement of the piston rod, preventing fluid leakage and maintaining system pressure.
材料
Premium-grade vegetable-tanned bovine leather with specific density (0.8-0.9 g/cm³)thickness tolerance ±0.1mmtreated with hydraulic fluid-resistant impregnation compounds. Leather must meet ASTM D1517 standards for industrial leather.
Hardness
70-80 Shore A
Diameter Range
10-200 mm
Compression Set
<15% after 24h at 70°C
Pressure Rating
Up to 25 MPa
Temperature Range
-20°C to +80°C
Fluid Compatibility
Mineral oils, HFA, HFB, HFC fluids
标准
ISO 3601-3DIN 3760ASTM D1517SAE J515

FMEA · 风险与缓解

诱因 → 失效模式 → 工程缓解

Exposure to incompatible hydraulic fluids->Swelling, cracking, or disintegration of leather material->Verify fluid compatibility before installation and use appropriate impregnation treatments
Excessive temperature operation->Hardening (low temp) or softening (high temp) leading to seal failure->Maintain operating temperature within specified range and monitor system temperature
Improper installation compression->Uneven wear, leakage, or premature failure->Follow manufacturer installation guidelines and use proper installation tools

常见问题

What is the maximum pressure rating for leather seal bodies?

Leather seal bodies typically handle up to 25 MPa (3625 psi) when properly installed in compatible hydraulic systems.

How does temperature affect leather seal performance?

Optimal performance occurs between -20°C to +80°C. Outside this range, leather may harden or soften, affecting sealing effectiveness.

Can leather seals be used with all hydraulic fluids?

They work best with mineral-based oils and certain synthetic fluids (HFA, HFB, HFC). Compatibility should be verified for specific fluid types.
