Sliding Components C120003866 is a precision mechanical component engineered exclusively for Hydraulic Rock Drills, designed to solve the core pain points of high friction, rapid wear, and unstable movement in harsh underground drilling environments. It plays a critical role in guiding and supporting key sliding parts—such as pistons, drill rod sleeves, and valve cores—ensuring smooth, efficient power transmission in hydraulic systems.
Crafted with high-grade wear-resistant alloy (42CrMo) and a surface PTFE coating, the component delivers exceptional durability and low friction performance. Its friction coefficient is as low as 0.08, reducing mechanical energy loss by 30% compared to standard sliding parts. The sliding surface undergoes precision grinding and honing processes, achieving a roughness of Ra≤0.8μm and a guiding accuracy tolerance of ±0.01mm, ensuring tight fit with Hydraulic Rock Drill assemblies.
Sliding Components C120003866 features a sealed structure with dust-proof and moisture-proof design, passing 72-hour salt spray tests to resist corrosion from underground moisture and abrasive debris. It also incorporates a vibration-absorbing buffer layer, mitigating the impact of high-frequency vibration during drilling on sliding parts. Each unit undergoes strict ISO 9001 quality control, including wear resistance tests (≥10,000 sliding cycles without deformation), dimensional accuracy checks via 3D scanning, and load-bearing capacity verification (up to 500kg).
The component offers universal compatibility with mainstream Hydraulic Rock Drill models, including Atlas Copco FlexiROC M15 and Sandvik DP1800, as well as most generic brands. Installation is hassle-free with a direct replacement design that matches original equipment specifications—no custom adjustments required, reducing maintenance downtime for mining teams. Backed by a 12-month warranty, Sliding Components C120003866 extends the service life of paired sliding parts by 45% compared to generic alternatives. Whether used in deep underground mines or open-pit drilling sites, it ensures stable sliding movement, minimizes component wear, and maximizes the overall operational efficiency and reliability of Hydraulic Rock Drill systems.
