Component Specifications

Definition
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.
Working Principle
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.
Materials
Premium-grade vegetable-tanned bovine leather with specific density (0.8-0.9 g/cm³), thickness tolerance ±0.1mm, treated with hydraulic fluid-resistant impregnation compounds. Leather must meet ASTM D1517 standards for industrial leather.
Technical Parameters
  • 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
Standards
ISO 3601-3, DIN 3760, ASTM D1517, SAE J515

Engineering Analysis

Risks & Mitigation
  • Leather degradation from incompatible fluids
  • Compression set over time reducing sealing force
  • Temperature extremes causing hardening or softening
  • Improper installation leading to premature failure
FMEA Triads
Trigger: Exposure to incompatible hydraulic fluids
Failure: Swelling, cracking, or disintegration of leather material
Mitigation: Verify fluid compatibility before installation and use appropriate impregnation treatments
Trigger: Excessive temperature operation
Failure: Hardening (low temp) or softening (high temp) leading to seal failure
Mitigation: Maintain operating temperature within specified range and monitor system temperature
Trigger: Improper installation compression
Failure: Uneven wear, leakage, or premature failure
Mitigation: Follow manufacturer installation guidelines and use proper installation tools

Frequently Asked Questions

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.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
