Pin C0430011241 is a critical connecting and torque-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 38G), abrasive rock dust, acidic slurry and drastic temperature swings. Yet, Pin C0430011241 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations.
First, its 40CrNiMoA steel core with carburizing treatment boosts surface hardness. This eliminates premature wear from continuous friction. Second, it withstands 40MPa alternating loads without deformation or fracture. Consequently, it prevents connection failure in high-pressure drill systems. Third, its ±0.003mm precision ensures tight fitting with mating components. Likewise, this avoids operational slack and torque loss.
Fourth, the integrated anti-loosening groove design locks the pin in place. Above all, this prevents vibration-induced disassembly during high-intensity drilling. Fifth, the multi-layer anti-corrosion coating (zinc-nickel plating + passivation) enhances durability. On top of that, it resists chemical erosion from acidic and alkaline mining environments.
Unlike ordinary pins, this model combines high-toughness steel with precision machining. To elaborate, the 40CrNiMoA steel provides impact resistance, while carburizing treatment delivers extreme surface wear resistance. Thus, it outperforms standard pins in service life by 90%.
Our manufacturing team uses precision turning + grinding technology for consistent dimensions. Furthermore, the surface undergoes carburizing treatment, boosting hardness to HRC 64-67. Additionally, the dimensional accuracy test ensures no deviation under extreme temperature changes.
Notably, it adapts to extreme temperatures from -80°C to 190°C. Moreover, it passes 260-hour salt spray tests with no rust or coating damage. In addition, it endures 500,000-cycle fatigue trials without performance degradation.
The pin’s press-fit + anti-loosening groove design integrates seamlessly with mainstream drill models. It requires no modifications to existing assemblies. As a result, maintenance teams can complete installation in 6 minutes using standard tools.
Our quality team conducts strict ISO 9001 verification for every unit. We perform load-bearing tests, torque transmission measurements, dimensional accuracy checks and anti-loosening trials. Importantly, it complies with ISO 8753 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 82%. Additionally, backed by a 12-month warranty, it cuts pin-related failure rates by 88%.
It not only extends drill system service life by 70% but also lowers annual maintenance costs by 50%. Overall, Pin C0430011241 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.
