Component Specifications

Definition
The Reinforcement Edge is a specialized structural element integrated into leather hydraulic piston seals, designed to provide mechanical support and prevent seal extrusion under dynamic hydraulic pressure. This component typically consists of a reinforced lip or flange that distributes stress evenly, maintains seal geometry during piston movement, and extends operational lifespan by reducing wear and deformation in high-pressure industrial applications.
Working Principle
The Reinforcement Edge operates by creating a rigid boundary that counteracts hydraulic pressure forces, preventing the flexible leather seal material from extruding into clearance gaps. During piston reciprocation, it maintains consistent contact pressure against the cylinder wall while allowing the seal to flex minimally, ensuring continuous sealing performance without compromising material integrity.
Materials
High-tensile synthetic polymers (polyurethane, PTFE composites), embedded steel or brass rings, or fiber-reinforced elastomers with hardness ratings of 80-95 Shore A.
Technical Parameters
  • Thickness 1.5-3.0 mm
  • Compression Set <15% after 24h at 100°C
  • Pressure Rating Up to 40 MPa
  • Tensile Strength ≥25 MPa
  • Temperature Range -40°C to +120°C
Standards
ISO 3601-1, DIN 3770

Frequently Asked Questions

What is the primary function of a Reinforcement Edge in hydraulic seals?

It prevents seal extrusion under high pressure by providing structural support to the leather material, maintaining seal integrity and extending service life.

Can Reinforcement Edges be replaced separately from the main seal?

Typically no—they are integrated during manufacturing, though some modular designs allow replacement, but this requires complete disassembly and professional installation.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
