3115350201 Extractor Liner,

3115 3502 01 Extractor Liner Atlas Copco

The 3115350201 Extractor Liner—also listed as 3115 3502 01 Extractor Liner Atlas Copco—is one of the most crucial internal wear components in Atlas Copco rock drill systems. Designed specifically to endure extreme pressure cycles, abrasive dust, high-frequency impact forces and continuous hydraulic load, this component plays a decisive role in maintaining the accuracy, stability and longevity of the entire drifter assembly.

For operators looking to extend machine lifespan, reduce maintenance interruptions and sustain drilling performance under the harshest mining and construction environments, the 3115350201 Extractor Liner is engineered to provide unmatched reliability. As an OEM-grade part supplied exclusively by 3GEN Export, it is readily available for global delivery within 5 working days, ensuring your operations never stall.

What Is the 3115350201 Extractor Liner?

The 3115350201 Extractor Liner Atlas Copco is a precision-manufactured cylindrical component that supports correct movement of the extractor assembly inside the rock drill. As part of the percussion mechanism, it helps ensure that the extractor operates smoothly, reducing the risk of binding, vibration misalignment or metal-to-metal wear.

Its internal geometry is carefully calibrated, and its multi-layered structure—featuring both hardened steel and bronze alloy surfaces—ensures optimal lubrication retention and mechanical stability.

Key Functions of the 3115 3502 01 Extractor Liner Atlas Copco

1. Precision Guidance for Extractor Movement

The liner stabilizes the extractor rod’s movement path, allowing it to operate under high-impact loads with minimal resistance.

2. Reduction of Surface Wear

The bronze-lined interior maintains a low-friction interface, decreasing the risk of premature component wear and ensuring longer operational life.

3. Thermal and Impact Protection

During rock drilling, extreme heat and impact waves travel through the drifter. The 3115350201 liner absorbs and distributes these forces, preventing structural fatigue.

4. Contamination Control

The tight tolerances and sealing properties help limit dust, rock particles and oil impurities from damaging inner components.

5. Efficiency Optimization

By maintaining ideal alignment and lubrication retention, this extractor liner improves overall drifter performance, allowing for consistent penetration rates and reduced downtime.

Technical Advantages of the 3115350201 Extractor Liner
