Comprehensive Seal Kit for Hydraulic Rock Drills
This seal kit is engineered to provide complete sealing solutions for hydraulic rock drills, ensuring leak-free operation in high-pressure systems exposed to mining contaminants. The kit combines FKM (Viton) and NBR rubber components to balance chemical resistance and flexibility, critical for maintaining performance in harsh drilling environments.

 

Key Components & Benefits
  • Material Selection:
    • FKM seals handle extreme temperatures (-20°C to +200°C) and resist mineral oils, hydraulic fluids (ISO 6743-4), and diesel—ideal for high-friction zones. NBR components offer cost-effective sealing in lower-temperature, non-aggressive circuits .
    • All components meet ASTM D1418 standards, ensuring consistent quality and compatibility with OEM specifications.
  • Precision & Compatibility:
    • 12-piece set includes O-rings (6mm to 20mm cross-sections), lip seals, and backup rings, all machined to ±0.05mm tolerance (ISO 3601-1). This precision ensures a tight fit in ISO 3601-3 grooves, reducing installation time by 40% compared to sourcing individual seals .
    • Designed for R38 hydraulic rock drills, the kit serves as a direct replacement for worn seals in impact mechanisms, hydraulic cylinders, and valve bodies.
  • Durability & Performance:
    • FKM components exhibit ≤20% compression set after 70 hours at 200°C (ASTM D395), maintaining sealing force over 5000 hours of operation. NBR elements provide excellent flexibility for static sealing applications .
    • Resistant to abrasion and humidity, the kit minimizes unplanned downtime from fluid leaks, protecting critical drill components like pistons and hydraulic lines.

 

Applications

 

  • Primary Use: R38 hydraulic rock drills in tunneling, quarrying, and mineral exploration.
  • Suitable For: Sealing hydraulic circuits, including impact mechanisms, feed cylinders, and rotary drives.
