Sliding Seal of the Bridge C110001009014 is a critical sealing component exclusively designed 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 muddy construction sites.
These settings pose unique challenges for seals: high hydraulic pressure, frequent sliding friction, abrasive rock dust, corrosive slurry and drastic temperature swings. These issues often cause seal deformation, leakage or premature wear, leading to costly hydraulic system failures. Yet, Sliding Seal of the Bridge C110001009014 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations.
First, its high-strength PU material + stainless steel skeleton resists compression deformation. This eliminates leakage caused by seal collapse under 40MPa hydraulic pressure. Second, the PU material’s low friction coefficient (0.06) reduces wear during sliding movement. Consequently, it extends service life even with frequent drill operation. Third, its ±0.02mm sealing precision ensures tight fit with bridge components. Likewise, this blocks micro-leakage that wastes hydraulic oil and reduces system efficiency.
Fourth, the double-lip + dust-proof lip integrated design provides multi-layer protection. Above all, the main lip seals hydraulic oil, while the dust-proof lip blocks rock dust and slurry, preventing internal component abrasion. Fifth, the PU material’s wide temperature adaptability (-50°C~150°C) ensures stable performance in extreme cold (high-altitude frozen mines) and heat (deep underground drilling). On top of that, the material is oil-resistant and aging-resistant, maintaining elasticity for long-term use.
Unlike ordinary sliding seals, this model is engineered for hydraulic rock drill bridge components’ dynamic working conditions. To elaborate, the stainless steel skeleton enhances structural rigidity, while the PU lip ensures flexible sealing contact. Thus, it outperforms standard seals in service life by 150%, significantly reducing leakage-related downtime.
Our manufacturing team uses precision molding + vulcanization technology for seamless integration of PU and steel skeleton. Furthermore, each unit undergoes pressure testing (40MPa) and wear resistance verification. Additionally, the seal surface undergoes polishing treatment to reduce friction with sliding components.
Notably, it adapts to extreme temperatures from -50°C to 150°C. Moreover, it passes 400-hour salt spray tests with no rust or material degradation. In addition, it endures 500,000-cycle sliding trials without leakage or lip damage.
The seal’s press-fit installation design integrates seamlessly with mainstream Hydraulic Rock Drill bridge components. It requires no modifications to existing assemblies. As a result, maintenance teams can complete replacement in 10 minutes using standard tools.
Our quality team conducts strict ISO 9001 verification for every unit. We perform sealing precision tests, pressure resistance trials, wear resistance inspections and corrosion resistance verification. Importantly, it complies with ISO 3601 international hydraulic seal standards.
Compatible with top Hydraulic Rock Drill brands, it serves as a direct OEM replacement. Thanks to its reliability, it reduces seal-related failure rates by 95%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 60%.
It not only extends hydraulic system service life by 100% but also ensures zero leakage in bridge components. Overall, Sliding Seal of the Bridge C110001009014 delivers cost-effective, reliable performance for long-term mining operations. Beyond that, it minimizes downtime caused by seal failures, maximizing operational efficiency and project profitability.
