SPGW Hydraulic Piston Seal | Compact Design for Excavator & Heavy Equipment Cylinders

High-Density Compact Piston Sealing Solution for Space-Constrained Applications

The SPGW Hydraulic Piston Seal represents advanced sealing technology specifically engineered for compact hydraulic cylinders where space optimization is critical. Featuring a robust single-acting design with integrated anti-extrusion elements, this seal delivers zero-leakage performancein demanding excavator applications while maintaining minimal installation space requirements.

Product Highlights

  • Ultra-Compact Profile - Optimized cross-section for space-limited cylinder designs
  • Integrated Anti-Extrusion - Built-in anti-extrusion functionality eliminates need for separate backup rings
  • Enhanced Wear Resistance - Premium polyurethane compound withstands abrasive environments
  • Easy Installation - Simplified groove design reduces assembly time and cost
  • Proven Performance - Millions of cycles in field-tested excavator applications

Technical Specifications

Size Standard or Customized Origin China
Product name Piston Seals Temperature -30℃ ~100℃
Application Excavator Type SPGW
Pressure ≤ 400 bar Speed ≤ 1.5 m/s
Material bronze filled PTFE,POM and NBR Color brown

Applications

Heavy Equipment & Machinery

  • Excavator Hydraulic Cylinders - Boom, arm, and bucket applications
  • Construction Machinery - Bulldozers, loaders, compactors
  • Agricultural Equipment - Tractor implements, harvesters
  • Mining Equipment - Underground and surface mining machinery

Industrial Applications

  • Compact Hydraulic Presses
  • Injection Molding Machines
  • Material Handling Equipment
  • Industrial Automation Systems

Design Advantages

Space-Optimized Engineering

  • Compact Cross-Section - 15-30% space savings compared to conventional piston seals
  • Integrated Design - Combines sealing and anti-extrusion in single component
  • Optimized Groove Dimensions - Simplified machining requirements
  • Reduced Part Count - Eliminates need for additional backup components

Performance Enhancements

  • Low-Friction Design - Optimized lip geometry reduces stick-slip
  • Pressure-Activated Sealing - Enhanced sealing with increasing system pressure
  • Contamination Tolerance - Effective performance in moderately contaminated fluids
  • Thermal Stability - Maintains sealing integrity across operating temperature range

Material Science

Reinforced Polyurethane Compound

  • Abrasion Resistance - 5-8x longer wear life than standard NBR
  • Tear Strength - Superior mechanical properties prevent installation damage
  • Hydrolytic Stability - Consistent performance in water-containing fluids
  • Aging Resistance - Maintains properties through extended service life

Alternative Material Options

  • PTFE Composites - For ultra-low friction and high-temperature applications
  • HNBR Compounds - Enhanced chemical and temperature resistance
  • Custom Formulations - Tailored to specific application requirements

Installation & Maintenance

Installation Guidelines

  • Groove Preparation - Ensure clean, deburred groove surfaces
  • Lubrication - Apply compatible lubricant to seal surfaces
  • Careful Handling - Use installation tools to prevent lip damage
  • Proper Orientation - Install with pressure side facing correct direction
  • Initial Testing - Conduct low-pressure break-in before full operation

Maintenance Recommendations

  • Regular Inspection - Monitor during routine cylinder maintenance
  • Fluid Management - Maintain proper fluid cleanliness and filtration
  • Preventive Replacement - Replace during scheduled overhaul periods
  • Documentation - Keep installation records for service history
