Steel Disc C110002153014 is a critical torque-bearing and power-transmission component for Hydraulic Rock Drills. It excels in extreme mining environments—for instance, deep underground ore mines, high-altitude hard rock quarries, large-scale tunnel boring projects and high-intensity drilling sites.
These settings pose unique challenges for steel discs: high alternating torque, continuous friction-induced heat, abrasive rock dust, and occasional impact loads, which often cause disc warping, wear, or cracking. Yet, Steel Disc C110002153014 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations and lead to equipment downtime.
First, its 42CrNiMoA alloy steel core with quenching-tempering dual treatment achieves HRC 58-62 surface hardness. This eliminates premature wear from high-speed friction with brake components. Second, it withstands 500N·m peak torque without deformation or torsion failure. Consequently, it ensures stable torque transmission for drill braking and rotation functions. Third, its ±0.03mm flatness precision guarantees uniform contact with mating parts. Likewise, this avoids local stress concentration and reduces brake noise.
Fourth, the precision grinding surface (Ra ≤0.8μm) reduces friction coefficient and heat buildup. Above all, this prevents thermal deformation during continuous braking, extending service life. Fifth, the multi-layer anti-corrosion coating (zinc-nickel plating + passivation) resists chemical erosion. On top of that, it blocks rust and abrasion from rock dust, hydraulic oil, and acidic mining slurry, ensuring long-term reliability.
Unlike ordinary steel discs, this model is engineered for hydraulic rock drill’s high-load dynamic working conditions. To elaborate, the 42CrNiMoA steel balances high hardness and toughness, while the quenching-tempering treatment enhances fatigue resistance. Thus, it outperforms standard steel discs in service life by 150%, significantly reducing replacement-related downtime.
Our manufacturing team uses precision forging + CNC grinding technology for consistent dimensions. Furthermore, each unit undergoes hardness testing (HRC 58-62) and flatness verification. Additionally, the disc undergoes dynamic balancing tests (≤0.05g·mm) to avoid vibration during high-speed operation.
Notably, it adapts to extreme temperatures from -50°C (high-altitude frozen mines) to 180°C (continuous braking heat). Moreover, it passes 400-hour salt spray tests with no rust or coating peeling. In addition, it endures 100,000-cycle torque fatigue trials without performance degradation.
The steel disc’s bolt-on mounting design integrates seamlessly with mainstream Hydraulic Rock Drill transmission/braking systems. It requires no modifications to existing assemblies. As a result, maintenance teams can complete replacement in 15 minutes using standard tools.
Our quality team conducts strict ISO 9001 verification for every unit. We perform hardness tests, torque-bearing trials, flatness inspections and corrosion resistance verification. Importantly, it complies with ISO 6405 international steel component standards.
Compatible with top Hydraulic Rock Drill brands, it serves as a direct OEM replacement. Thanks to its reliability, it reduces steel disc-related failure rates by 95%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 60%.
It not only extends drill transmission system service life by 100% but also ensures stable braking and power transmission. Overall, Steel Disc C110002153014 delivers cost-effective, reliable performance for long-term mining operations. Beyond that, it minimizes downtime caused by disc failures, maximizing operational efficiency and project profitability.
