GLY-Type Piston Rod Seal

GLY Series: Graphene-Layered Y-Seal System

Product Overview
The GLY (Graphene-Layered Y-Seal) represents a breakthrough in high-performance rod sealing through advanced nanotechnology. By integrating atomically-thin graphene layers into a precision Y-shaped geometry, GLY seals deliver unparalleled thermal conductivity, strength, and sealing stability for extreme-duty applications.

Core Innovation: Graphene Matrix Architecture

  • Nano-Reinforced Structure: Multi-layer graphene platelets (5-10 atomic layers) embedded in polyurethane matrix

  • Anisotropic Design: Controlled graphene alignment provides directional strength (500% increase radially) while maintaining axial flexibility

  • Thermal Superhighway: Continuous graphene networks achieve 450 W/m·K thermal conductivity, dissipating friction heat instantly

Unique Advantages

  1. Heat-Free Operation: 95% of friction heat dissipated radially, preventing thermal degradation

  2. Zero Cold-Flow: Graphene reinforcement eliminates extrusion even at maximum pressure

  3. Universal Compatibility: Chemically inert graphene structure works with all hydraulic fluids and aggressive media

  4. Predictable Wear: Self-lubricating graphene layers wear at consistent 0.1μm per 1,000 hours

Smart Features

  • Thermal Monitoring: Embedded graphene sensors provide real-time temperature mapping

  • Wear Indicators: Gradual color change signals remaining service life

  • Installation Guidance: Directional graphene alignment ensures correct orientation

Applications

  • High-speed hydraulic presses (reduced cycle time by 18%)

  • Mobile equipment in extreme climates (proven at -55°C to +85°C ambient)

  • Clean energy systems (wind turbine pitch controls, hydraulic energy storage)

  • Aerospace actuators (certified for 25,000 PSI systems)

Sustainability Benefits

  • 70% longer service life reduces replacement frequency

  • Non-hazardous materials (REACH/ROHS compliant)

  • 40% energy savings through reduced friction

  • Fully recyclable through graphene recovery process

Installation & Service

  • Single-unit design replaces complex multi-part seals
