High-Performance Floating Seal Kit for Rock Drill Jumbos
Engineered for extreme mining environments, this floating seal kit ensures reliable sealing in wheel hubs and track systems of rock drill jumbos. The kit features tungsten carbide sealing rings and NBR O-rings, providing exceptional resistance to abrasion, mud ingress, and high-pressure washdowns .

 

Technical Specifications & Design

 

  • Core Components:
    • Tungsten Carbide Rings: Precision-machined with 0.8μm surface roughness, offering superior hardness (HRA 89-92) and wear resistance in abrasive mining conditions.
    • NBR O-Rings: 70 Shore A hardness with 18MPa extrusion resistance, compliant with ASTM D2000 M1 B1 for oil and fuel compatibility.
    • Self-Aligning Design: Allows for misalignment up to 0.5°, ensuring consistent sealing performance in dynamic applications.

 

Performance Advantages
  • High-Pressure Resistance: Capable of withstanding 1.5 MPa dynamic pressure, suitable for heavy-duty mining equipment.
  • Wide Temperature Range: Operates reliably from -30°C to +100°C, adapting to extreme climate conditions in underground and surface mines.
  • Longevity: Passed 5,000-hour mud immersion test, significantly reducing maintenance frequency compared to standard seals.

 

Applications
  • Rock Drill Jumbos: Restores sealing efficiency in Sandvik DT922i, DL421, and compatible drill rig wheel hubs.
  • Mining Equipment: Used in track systems, gearboxes, and axle assemblies requiring robust sealing against contaminants.
  • Construction Machinery: Suitable for loaders, excavators, and bulldozers operating in harsh environments.
