Product Overview

The 3115535800 LINER ATLAS COPCO is constructed from high-grade alloy steel with specialized surface treatments, ensuring optimum hardness, wear resistance, and dimensional stability. Serving as the guide and containment cylinder for the piston in the rock drill assembly, it plays a key role in absorbing axial stresses, maintaining alignment, and preventing excessive friction during high-frequency operations.

This liner is engineered to maintain structural integrity under extreme conditions—including high pressure, cyclic impact, and abrasive contaminants—common in surface and underground mining, tunneling, and quarrying applications.

Functionality in Rock Drills

The 3115535800 LINER ATLAS COPCO is a cylindrical guide inside which the rock drill piston reciprocates. It must ensure:

• Consistent axial alignment of the piston

• Efficient compression of hydraulic fluids

• Reduced wear on piston and internal chamber walls

• Noise and vibration minimization during drilling

Thanks to the high-performance surface finish and corrosion-resistant design, the liner minimizes oil leakage and ensures optimal performance over extended drilling cycles.
