Shaft C1100009401 is a critical power-transmitting component for Hydraulic Rock Drills. It excels in extreme mining environments—for instance, deep underground ore mines, high-altitude hard rock quarries and large-scale tunnel boring projects.
These settings pose intense vibration (up to 42G), abrasive rock dust, acidic slurry and drastic temperature swings. Yet, Shaft C1100009401 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations.
First, its 42CrNiMoA steel core with dual heat treatment boosts surface hardness. This eliminates premature wear from gear meshing and component friction. Second, it delivers 500N·m torque without deformation or torsion failure. Consequently, it ensures consistent power transmission in high-load drill systems. Third, its ±0.005mm precision guarantees tight fitting with bearings and gears. Likewise, this avoids operational slack and torque loss during drilling.
Fourth, the multi-groove lubrication design retains oil for continuous lubrication. Above all, this reduces friction coefficient and extends service life in harsh, low-maintenance environments. Fifth, the triple anti-corrosion coating (chrome plating + passivation + sealant) enhances durability. On top of that, it resists chemical erosion from hydraulic oil and acidic mining slurry.
Unlike ordinary shafts, this model combines high-toughness steel with dual heat treatment. To elaborate, the 42CrNiMoA steel provides impact resistance, while carburizing-nitriding treatment delivers extreme surface wear resistance. Thus, it outperforms standard shafts in service life by 100%.
Our manufacturing team uses precision turning + grinding + balancing technology. Furthermore, the surface undergoes carburizing-nitriding treatment, boosting hardness to HRC 62-65. Additionally, dynamic balancing tests ensure vibration-free operation at high speeds.
Notably, it adapts to extreme temperatures from -90°C to 210°C. Moreover, it passes 300-hour salt spray tests with no rust or coating damage. In addition, it endures 600,000-cycle fatigue trials without performance degradation.
The shaft’s spline connection design integrates seamlessly with mainstream drill models. It requires no modifications to existing power transmission assemblies. As a result, maintenance teams can complete installation in 8 minutes using standard tools.
Our quality team conducts strict ISO 9001 verification for every unit. We perform torque tests, dimensional accuracy checks, wear resistance trials and corrosion resistance inspections. Importantly, it complies with ISO 7653 international mining equipment standards.
Compatible with top Hydraulic Rock Drill brands, it serves as a direct OEM replacement. Thanks to its durability, it reduces replacement frequency by 88%. Additionally, backed by a 12-month warranty, it cuts shaft-related failure rates by 92%.
It not only extends drill system service life by 80% but also lowers annual maintenance costs by 55%. Overall, Shaft C1100009401 delivers cost-effective, reliable performance for long-term mining operations. Beyond that, it supports high-intensity drilling tasks in the most demanding conditions, maximizing operational efficiency.
