Heavy-Duty Nylon Spacer Sleeve for Rock Drill Jumbos
Engineered for extreme mining environments, this spacer sleeve ensures reliable separation and protection of hydraulic hoses in rock drill jumbos. Constructed from high-strength nylon 6/6, it offers superior resistance to abrasion, chemical corrosion, and mechanical stress, making it ideal for heavy-duty applications .

 

Technical Specifications & Design
  • Core Components:
    • Nylon 6/6 Material: Compliant with ASTM D638, providing 78 MPa tensile strength and 105 MPa compressive strength, ensuring long-term durability in high-vibration conditions.
    • Precision Machining: Tolerances of ±0.05 mm and 0.8μm Ra surface finish minimize friction and prevent hose wear during dynamic movements.
    • Interlocking Grooves: Designed to secure multiple hydraulic hoses (15-25 mm diameter) in parallel, eliminating entanglement and optimizing space utilization.

 

Performance Advantages
  • Temperature Resistance: Operates reliably from -20°C to +120°C, suitable for both cold underground mines and high-temperature surface applications.
  • Lightweight Design: Weighing just 0.05 kg per piece, it reduces overall equipment load while maintaining structural integrity.
  • Low Maintenance: Self-lubricating properties of nylon 6/6 eliminate the need for additional lubricants, reducing downtime and maintenance costs.

 

Applications
  • Hydraulic Systems: Used in rock drill jumbo 推进梁 to separate and protect high-pressure hoses, preventing damage from vibration and abrasion.
  • Mining Equipment: Compatible with Sandvik DT922i, DL421, and similar drill rigs, ensuring seamless integration with existing hydraulic layouts.
  • Construction Machinery: Ideal for excavators, loaders, and bulldozers requiring robust hose management solutions in harsh conditions.
