Nitrided Alloy Steel Head Housing
Engineered to provide structural integrity and vibration resistance in high-stress hydraulic rock drilling applications, this head housing is critical for maintaining stability in UD391 series underground mining equipment.

 

Technical Specifications & Design
Constructed from SAE 4140 alloy steel with a nitrided surface (HV 500 hardness), the housing offers exceptional resistance to wear and fatigue under continuous operation. The 220 mm length (ISO 1133 H7 tolerance) and M24 x 2.0 threaded ports (SAE J514 compliant) ensure compatibility with standard hydraulic connections. The dual-layer design—combining a rigid steel core with a shock-absorbing rubberized inner sleeve—minimizes lateral movement and reduces stress on adjacent components.

 

Performance Advantages

 

  • Pressure Stability: Maintains alignment at 300 bar continuous pressure, with a 350 bar burst pressure rating for safety redundancy.
  • Vibration Dampening: Rubberized inner sleeve absorbs percussion energy, extending service life of drill rods and hydraulic hoses.
  • Ease of Installation: Threaded ports allow quick mounting without specialized tools, reducing downtime during maintenance.

 

Applications

 

  • Underground Mining: Essential for supporting hydraulic rock drills in UD391 series rigs during tunnel boring and rock excavation.
  • Heavy Machinery: Used in excavators and loaders to stabilize hydraulic systems in impact-driven tasks.
  • Industrial Hydraulics: Supports material handling systems and presses, ensuring precision in high-frequency operations.
