Heavy-Duty Front Steering for Hydraulic Rock Drills This front steering component is engineered to control directional movement of hydraulic rock drill heads, ensuring precise positioning in mining and construction environments. Constructed from 42CrMo4 alloy steel with induction hardening, it balances structural strength and impact resistance, critical for withstanding vibration and axial loads during drilling operations.
Key Performance Attributes
Material & Durability:
42CrMo4 alloy steel provides 1100MPa tensile strength, supporting 100kN axial loads without deformation. The induction-hardened surface (3mm depth) resists wear from repetitive movement, extending service life by 35% compared to carbon steel alternatives .
8μm zinc-nickel plating (ASTM B841) offers 500-hour salt spray resistance (ASTM B117), protecting against corrosion in damp underground mines .
Precision & Control:
IT7 dimensional tolerance (ISO 286-1) ensures smooth pivot movement, with ±0.05mm parallelism minimizing steering backlash. Sealed bearings prevent contamination by rock dust, maintaining responsiveness over 1.5×10⁶ cycles .
Operational Reliability:
The -30°C to +120°C operating range ensures performance stability in extreme conditions, from cold tunnels to high-friction steering systems. Its modular design allows easy integration with standard hydraulic rock drill front assemblies, reducing maintenance downtime .
Applications
Hydraulic Rock Drills: Critical for directional control of drill heads in tunneling, quarrying, and mineral exploration.
Mining Equipment: Compatible with surface and underground drilling rigs requiring precise front-end positioning.
