What Is the Function of a Rock Drill Liner?
Structural Guidance and Surface Protection
Inside hydraulic rock drills, liners act as controlled contact surfaces. They guide internal motion while preventing direct friction between major assemblies. The liner absorbs operational stresses that would otherwise affect expensive internal components.

The 3115347400, 3115 3474 00 LINER ATLAS COPCO stabilizes movement during percussion cycles and ensures that rotating and sliding elements maintain correct positioning throughout operation.

Wear Management in High-Impact Operations
Rock drilling produces extreme mechanical stress. Continuous hammering generates vibration, heat, and micro-abrasion. The liner distributes these forces evenly, reducing localized stress concentration and extending overall equipment lifespan.

Engineering Design and Material Characteristics
Precision Machined Body
The component visible in the images features a cylindrical configuration with carefully machined grooves and lubrication channels. These design details allow proper oil distribution across internal surfaces, reducing friction and maintaining operational smoothness.

Key design characteristics include:

• High dimensional accuracy
• Balanced wall thickness for strength
• Optimized lubrication flow paths
• Stable seating geometry
• Resistance to deformation under load

Advanced Material Composition
The liner is manufactured using hardened alloy steel combined with wear-resistant internal surfaces. This construction ensures:

• High fatigue resistance
• Reduced surface scoring
• Long operational service intervals
• Stability under thermal expansion

Such properties are essential for drilling machines operating continuously in harsh environments.

Performance Advantages in Field Applications
Improved Operational Stability
Proper alignment is critical for drilling efficiency. A worn or incorrectly machined liner causes vibration imbalance and energy loss. This component maintains accurate positioning, allowing percussion energy to transfer efficiently to the drill string.

Reduced Maintenance Frequency
Because the liner absorbs wear instead of surrounding assemblies, maintenance cycles become more predictable. Operators benefit from:

• Lower downtime
• Reduced repair costs
• Longer service intervals

Consistent Hydraulic Efficiency
Smooth internal surfaces help maintain correct hydraulic pressure flow. Stable pressure improves drilling penetration rates and enhances machine productivity.
