High-Precision Guiding Ring for Hydraulic Rock Drills This guiding ring ensures precise alignment of drill shanks in hydraulic rock drills, critical for reducing vibration and extending tool life in abrasive mining environments. Its phosphor bronze construction (ASTM B148 C54400) balances low friction with high compressive strength, making it ideal for high-speed drilling operations.
Key Features & Benefits
Material Performance:
Phosphor bronze (95% copper, 5% tin) offers superior wear resistance and thermal conductivity, minimizing heat buildup during continuous use. The HB180-200 hardness provides durability without compromising ductility, preventing cracking under lateral loads .
Precision Engineering:
IT5 dimensional tolerance (ISO 286-1) and 0.02mm maximum radial runout ensure consistent alignment with R32 drill shanks (ISO 10424-1). This precision reduces uneven wear on both the ring and shank, lowering maintenance costs by 30% compared to standard guiding components .
Polished surface (Ra 0.4μm) and integral lubrication grooves maintain a stable friction coefficient, even in dusty or damp conditions.
Operational Reliability:
Rated for 500,000 cycles under standard drilling conditions, it withstands the repetitive forces of hydraulic impact mechanisms. The wide temperature range (-20°C to +120°C) ensures performance stability in cold underground mines and high-friction drilling zones .
Applications
Primary use in hydraulic rock drills for tunneling, quarrying, and mineral exploration.
Compatible with R32 shank systems in mining equipment, including tunnel boring machines and surface drill rigs.
