High-Strength Alloy Steel Hole Drill Cover for Hydraulic Rock Drills
Engineered for extreme underground mining conditions, this drill cover ensures reliable protection in high-vibration hydraulic rock drill applications. Constructed from quenched & tempered alloy steel with 1200 MPa tensile strength, it withstands continuous dynamic loads while resisting abrasion and corrosion in harsh environments .

 

Technical Specifications & Design
The cover features a 60 mm diameter and 12 mm thickness (ISO 2768-mk tolerance), designed for secure mounting in hydraulic cylinder assemblies and drill rig components. Its zinc-nickel plating (10 μm thickness) passes 1000+ hours of salt spray testing, ensuring long-term performance in wet or corrosive mining environments . The 8-point bolt pattern with 30 N·m torque requirement simplifies installation and reduces downtime .

 

Performance Advantages
  • Vibration Resistance: Engineered to maintain dimensional stability in high-frequency oscillating systems, minimizing loosening in critical hydraulic connections.
  • Corrosion Protection: Zinc-nickel plating exceeds industry standards, extending service life by 50% compared to standard galvanized coatings .
  • Precision Fit: Dimensions adhere to ISO 2768-mk tolerances, ensuring compatibility with standard hydraulic system components.
  • Ease of Installation: Recommended torque specification streamlines assembly and maintenance processes.

 

Applications
  • Underground Mining: Critical for protecting hydraulic connections in rock drills used in tunnel boring and ore extraction.
  • Heavy Machinery: Used in excavators and loaders to shield high-pressure pivot points from debris.
  • Industrial Hydraulics: Supports presses and material handling equipment, ensuring structural integrity in repetitive motion tasks.
