Heavy-Duty O-Ring for Rock Drill Jumbos
This O-ring is engineered to prevent fluid leakage in high-pressure hydraulic systems of rock drill jumbos, withstanding extreme temperatures, pressure surges, and exposure to abrasive mining contaminants. Its robust FKM construction ensures long-term sealing integrity, reducing maintenance downtime and protecting critical components like hydraulic cylinders and valves.

 

Technical Specifications & Design

 

  • Material & Chemical Resistance:
    • Constructed from FKM (fluorocarbon rubber) compound, compliant with ASTM D1418, offering exceptional resistance to mineral oils, hydraulic fluids (ISO 6743-4), diesel, and greases. Unlike standard NBR seals, FKM retains 96% of its elasticity after 1000 hours of immersion in harsh mining fluids .
    • The material’s stability across -20°C to +200°C makes it suitable for both cold underground mines and high-friction hydraulic circuits, where conventional rubber seals would degrade .
  • Sealing Performance:
    • 5mm cross-section with ±0.08mm tolerance (ISO 3601-1) ensures a tight fit in standard seal grooves, providing effective sealing at pressures up to 25MPa—critical for withstanding peak pressures in rock drill jumbo hydraulic systems .
    • 70 Shore A hardness balances flexibility and durability, maintaining contact force even after repeated compression cycles, with a compression set of ≤20% (ASTM D395) to ensure long-term efficiency .
  • Environmental Adaptability:
    • Resistant to ozone, aging, and humidity, ensuring longevity in damp underground environments. Its compatibility with ISO 3601-3 grooves simplifies installation and replacement in most rock drill jumbo models .

 

Applications

 

  • Rock Drill Jumbos: Seals hydraulic connections in drill arm mechanisms, propulsion systems, and valve bodies.
  • Mining Equipment: Compatible with loaders, crushers, and tunneling machines requiring high-pressure hydraulic seals.
  • Industrial Hydraulics: Suitable for heavy-duty presses, injection molding machines, and steel mill systems.
