High-Precision Alloy Steel Seal Housing for Hydraulic Rock Drills
Engineered for extreme underground mining conditions, this seal housing ensures reliable performance in high-vibration hydraulic rock drill systems. Constructed from 20CrMnTi alloy steel with 58-62 HRC surface hardness and 1200 MPa tensile strength, it withstands continuous dynamic loads while resisting abrasion and corrosion in harsh environments .

 

Technical Specifications & Design
The seal housing adheres to DIN ISO 7181 standards (38 mm inner diameter, 55 mm outer diameter, 80 mm length) for precision fit in hydraulic cylinder assemblies and drill rig components . Its nitrided surface treatment (0.3-0.5 mm layer depth, 1000 HV hardness) provides superior wear resistance, extending service life by 40% compared to standard electroplated coatings . The 180 N·m threaded connection torque and 350 MPa maximum working pressure make it suitable for heavy-duty hydraulic applications .

 

Performance Advantages
  • Vibration Resistance: Engineered to maintain dimensional stability in high-frequency oscillating systems, minimizing wear in critical hydraulic connections.
  • Corrosion Protection: Nitrided surface exceeds industry standards, providing long-term durability in wet or corrosive mining environments.
  • Precision Fit: DIN ISO 7181 dimensions ensure compatibility with standard hydraulic system components.
  • Ease of Installation: Clear torque specifications streamline maintenance processes.

 

Applications
  • Underground Mining: Critical for securing high-pressure hydraulic lines in rock drills used in tunnel boring and ore extraction.
  • Heavy Machinery: Used in excavators and loaders to maintain structural integrity in dynamic hydraulic systems.
  • Industrial Hydraulics: Supports presses and material handling equipment, ensuring consistent pressure retention in repetitive motion tasks.
