Drive Shaft C1100019851 is a premium ultra-high-torque transmission component exclusively designed for Hydraulic Rock Drills. It excels in the most extreme mining environments—for example, deep underground metal mines, high-altitude hard rock quarries, large-scale tunnel boring projects and offshore drilling sites.
These settings pose unprecedented challenges: intense vibration (up to 52G), abrasive rock dust, corrosive acidic slurry and drastic temperature swings. Yet, Drive Shaft C1100019851 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations and cause costly downtime.
First, its 42CrNiMoVAA alloy steel core with carburizing-nitriding dual heat treatment boosts surface hardness to HRC 67-70. This eliminates premature wear from high-speed gear meshing and continuous friction. Second, it delivers 800N·m peak torque without deformation or torsion failure. Consequently, it ensures consistent power transmission in ultra-high-load drill systems, even during heavy-duty drilling cycles. Third, its ±0.001mm ultra-precision guarantees tight fitting with bearings and drive gears. Likewise, this avoids operational slack, abnormal noise and torque loss that reduce drilling efficiency.
Fourth, the spiral + micro-oil groove + nano-lubricant composite design retains hydraulic oil for long-lasting, self-lubricating performance. Above all, this reduces the friction coefficient by 45% and extends service life in low-maintenance mining environments. Fifth, the seven-layer anti-corrosion coating (titanium nitride + passivation + sealant + anti-rust oil + electrophoretic coating + ceramic layer + nano-protective film) provides all-around protection. On top of that, it resists chemical erosion from hydraulic oil, acidic slurry, humid underground air and even saltwater in offshore applications.
Unlike ordinary drive shafts, this model combines high-toughness steel with dual heat treatment and advanced nano-technology. To elaborate, the 42CrNiMoVAA steel provides superior impact resistance, while carburizing-nitriding treatment delivers extreme surface wear resistance. Thus, it outperforms standard drive shafts in service life by 140%, significantly reducing replacement frequency.
Our manufacturing team uses precision turning + grinding + dynamic balancing technology to ensure consistent dimensions. Furthermore, the surface undergoes strict quality control to meet ultra-precision standards. Additionally, dynamic balancing tests (≤0.005g·mm) ensure vibration-free operation at high speeds, protecting other drill components from damage.
Notably, it adapts to extreme temperatures from -110°C (polar or high-altitude regions) to 250°C (high-load drilling). Moreover, it passes 400-hour salt spray tests with no rust or coating damage. In addition, it endures 800,000-cycle fatigue trials without performance degradation, proving its reliability in long-term operations.
The drive shaft’s spline connection + keyway design integrates seamlessly with mainstream Hydraulic Rock Drill models. It requires no modifications to existing power transmission assemblies. As a result, maintenance teams can complete installation in 4 minutes using standard tools, minimizing downtime.
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 7653-5 international mining equipment standards, ensuring compatibility and safety.
Compatible with top Hydraulic Rock Drill brands, it serves as a direct OEM replacement. Thanks to its durability, it reduces replacement frequency by 94%. Additionally, backed by a 12-month warranty, it cuts drive shaft-related failure rates by 97%.
It not only extends drill system service life by 100% but also lowers annual maintenance costs by 65%. Overall, Drive Shaft C1100019851 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 and profitability for mining enterprises.
