Drive Shaft C1100018151 is a top-tier high-torque transmission component for Hydraulic Rock Drills. It excels in extreme mining environments—for instance, deep underground metal mines, high-altitude hard rock quarries and large-scale tunnel boring projects.
These settings pose intense vibration (up to 50G), abrasive rock dust, acidic slurry and drastic temperature swings. Yet, Drive Shaft C1100018151 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations.
First, its 42CrNiMoVA steel core with dual heat treatment boosts surface hardness. This eliminates premature wear from high-speed gear meshing and continuous friction. Second, it delivers 750N·m peak torque without deformation or torsion failure. Consequently, it ensures consistent power transmission in ultra-high-load drill systems. Third, its ±0.002mm precision guarantees tight fitting with bearings and drive gears. Likewise, this avoids operational slack, noise and torque loss during high-intensity drilling.
Fourth, the spiral + micro-oil groove composite lubrication design retains hydraulic oil for long-lasting lubrication. Above all, this reduces friction coefficient by 40% and extends service life in low-maintenance mining environments. Fifth, the six-layer anti-corrosion coating (titanium nitride + passivation + sealant + anti-rust oil + electrophoretic coating + ceramic layer) enhances durability. On top of that, it resists chemical erosion from hydraulic oil, acidic slurry and humid underground air.
Unlike ordinary drive shafts, this model combines high-toughness steel with dual heat treatment. To elaborate, the 42CrNiMoVA steel provides superior impact resistance, while carburizing-nitriding treatment delivers extreme surface wear resistance. Thus, it outperforms standard drive shafts in service life by 130%.
Our manufacturing team uses precision turning + grinding + dynamic balancing technology. Furthermore, the surface undergoes carburizing-nitriding treatment, boosting hardness to HRC 66-69. Additionally, dynamic balancing tests (≤0.008g·mm) ensure vibration-free operation at high speeds.
Notably, it adapts to extreme temperatures from -105°C to 240°C. Moreover, it passes 380-hour salt spray tests with no rust or coating damage. In addition, it endures 750,000-cycle fatigue trials without performance degradation.
The drive shaft’s spline connection + keyway 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 5 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 7653-4 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 93%. Additionally, backed by a 12-month warranty, it cuts drive shaft-related failure rates by 96%.
It not only extends drill system service life by 95% but also lowers annual maintenance costs by 62%. Overall, Drive Shaft C1100018151 delivers cost-effective, reliable performance for long-term mining operations. Beyond that, it supports ultra-high-intensity drilling tasks in the most demanding conditions, maximizing operational efficiency.
