Bushing C0430011191 is a top-tier load-bearing and friction-reducing component for Hydraulic Rock Drills. It excels in extreme mining environments—for instance, deep underground mineral mines, high-altitude hard rock quarries and large-scale tunnel boring projects.
These settings pose intense vibration (up to 32G), abrasive rock dust, acidic slurry and drastic temperature swings. Yet, Bushing C0430011191 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations.
First, its TiN titanium nitride coating lowers the friction coefficient to 0.035. This eliminates premature wear from metal-to-metal contact. Second, the 40CrNiMoA steel core enables it to withstand 35MPa hydraulic pressure. Consequently, it prevents deformation and leakage in high-pressure drill systems. Third, its ±0.005mm precision ensures ultra-tight component alignment. Likewise, this avoids operational noise, energy loss and component damage.
Fourth, the five-layer lip seal design blocks dust, moisture, slurry and chemicals. Above all, this protects internal drill components from corrosion and abrasive wear. Fifth, the dual anti-corrosion treatment (nitriding + TiN coating) enhances durability. On top of that, it resists chemical erosion from acidic and alkaline mining environments.
Unlike ordinary bushings, this model combines high-toughness steel with a super-hard TiN coating. To elaborate, the 40CrNiMoA steel provides impact resistance, while the TiN coating delivers extreme wear resistance. Thus, it outperforms standard bushings in service life by 80%.
Our manufacturing team uses precision honing + grinding technology for consistent dimensions. Furthermore, the surface undergoes plasma nitriding treatment, boosting hardness to HRC 62-65. Additionally, the coating adhesion test ensures no peeling under intense vibration or temperature changes.
Notably, it adapts to extreme temperatures from -70°C to 170°C. Moreover, it passes 220-hour salt spray tests with no rust or coating damage. In addition, it endures 400,000-cycle wear trials without performance degradation.
The bushing’s press-fit design integrates seamlessly with mainstream Hydraulic Rock Drill models. It requires no modifications to existing 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 pressure tests, friction coefficient measurements, dimensional accuracy checks and seal performance trials. Importantly, it complies with ISO 13715-4 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 75%. Additionally, backed by a 12-month warranty, it cuts bushing-related failure rates by 82%.
It not only extends drill system service life by 60% but also lowers annual maintenance costs by 45%. Overall, Bushing C0430011191 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.
