Compensation Cylinder C130001356 is a high-performance hydraulic pressure compensation component exclusively designed for Hydraulic Rock Drills. It excels in extreme mining environments—for instance, deep underground hard rock mines (≥800m depth), high-altitude quarries (≥2500m), tunnel construction sites and heavy-load drilling areas with uneven terrain.
These settings pose severe challenges for compensation cylinders: frequent hydraulic pressure spikes (up to 40MPa), uneven drill arm load (≥5000N), intense vibration (45G), abrasive rock dust, and drastic temperature swings. These issues often cause cylinder leakage, movement deviation, pressure compensation failure, piston rod bending, or corrosion, leading to drill instability and prolonged downtime. Yet, Compensation Cylinder C130001356 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations.
First, its 42CrMo alloy steel barrel + hard chrome-plated piston rod (Ra ≤0.08μm surface roughness) withstands 40MPa rated pressure and 80MPa burst pressure. This eliminates leakage or barrel deformation caused by pressure fluctuations in drill hydraulic systems. Second, the ±0.03mm movement precision ensures ultra-accurate pressure compensation for drill arm load. Consequently, it reduces drill vibration by 35% compared to standard cylinders and improves operation stability. Third, the dynamic load-balancing structural design distributes uneven drill arm force in real time. Likewise, this reduces piston rod stress and extends service life by 150%.
Fourth, the anti-shock design (reinforced piston rod + hydraulic dampened seal) withstands 45G vibration from high-intensity drill operation. Above all, this prevents seal damage and piston rod bending, ensuring continuous and reliable pressure compensation. Fifth, the wide temperature adaptability (-30°C~120°C) ensures stable performance in freezing high-altitude mines and hot underground drilling environments. On top of that, the IP66 dustproof/waterproof rating blocks rock dust and high-pressure water spray, protecting internal components from contamination and corrosion.
Unlike ordinary hydraulic cylinders, this model is engineered for Hydraulic Rock Drills’ heavy-load dynamic working conditions. To elaborate, the 42CrMo alloy steel barrel offers higher strength than standard carbon steel, while the dynamic load-balancing design matches the drill’s real-time arm movement requirements. Thus, it outperforms generic cylinders in service life by 160%, significantly reducing replacement-related downtime.
Our manufacturing team uses precision honing + multi-layer hard chrome plating technology for the barrel and piston rod. Furthermore, each unit undergoes 40MPa pressure testing (45 minutes) and 100% leak verification. Additionally, the cylinder undergoes 100,000-cycle compensation trials to ensure no movement deviation or performance degradation.
Notably, it adapts to extreme temperatures from -30°C (high-altitude cold regions) to 120°C (high-load drill hydraulic systems). Moreover, the piston rod passes 600-hour salt spray tests with no rust or plating peeling. In addition, the high-quality FKM seals endure 8,000-hour oil immersion trials without aging or leakage.
The cylinder’s flange mounting design integrates seamlessly with mainstream Hydraulic Rock Drill arm systems. It requires no modifications to existing hydraulic pipelines or brackets. As a result, maintenance teams can complete replacement in 20 minutes using standard tools.
Our quality team conducts strict ISO 9001 verification for every unit. We perform pressure resistance tests, movement precision inspections, anti-shock trials, leak verification and corrosion resistance testing. Importantly, it complies with ISO 6020/2 and SAE J1453 international hydraulic cylinder standards.
Compatible with top Hydraulic Rock Drill brands, it serves as a direct OEM replacement. Thanks to its reliability, it reduces cylinder-related failure rates by 94%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 60%.
It not only ensures stable hydraulic pressure compensation for drill operations but also extends the service life of drill arm systems by 90%. Overall, Compensation Cylinder C130001356 delivers cost-effective, high-performance results for long-term mining operations. Beyond that, it minimizes downtime caused by cylinder failure, maximizing operational efficiency and project profitability.
