3115347500, 3115 3475 00 LINER ATLAS COPCO

Introduction

The 3115347500 , 3115 3475 00 LINER ATLAS COPCO is a critical precision-engineered component designed to deliver maximum performance, durability, and accuracy in Atlas Copco rock drill assemblies. As one of the most essential wear parts in the drilling mechanism, the liner maintains the correct alignment and spacing of the internal moving components, ensuring efficient energy transfer from the piston to the drill bit.

Manufactured from high-grade alloy steel and finished with a bronze inner sleeve, this liner offers exceptional resistance against friction, wear, and deformation under extreme load conditions. 3GEN Export supplies this part as an OEM-equivalent replacement, providing world-class quality with global delivery in just 5 working days.

Product Overview

The 3115347500 LINER ATLAS COPCO functions as a cylindrical bearing surface inside the drifter mechanism, specifically designed to guide and stabilize the reciprocating piston during impact operations. Its main purpose is to maintain the precise alignment of the piston within the hammer housing, minimizing lateral movement and ensuring consistent percussive force transmission.

A properly engineered liner not only enhances drilling precision but also extends the lifespan of other associated components, such as the piston, chuck bushing, and cylinder. The bronze interior ensures smooth motion, while the hardened outer structure maintains mechanical integrity even under continuous shock loads.

This part has been optimized through advanced metallurgical treatments and precision machining processes that align with Atlas Copco’s rigorous engineering standards.

Technical Specifications

Function and Role in Drilling Mechanism

The 3115347500 LINER ATLAS COPCO plays a central role in ensuring mechanical balance and precision within the impact chamber. When the rock drill operates, the piston reciprocates at high velocity to deliver impact energy to the drill bit. The liner forms the main guiding bore that ensures each stroke remains perfectly linear and aligned.

By minimizing clearance between the piston and cylinder wall, the liner:

• Prevents mechanical wobble and misalignment.

• Reduces metal-to-metal friction.

• Ensures efficient energy transfer during impact.

• Maintains pressure consistency in hydraulic and pneumatic systems.

Without this precise liner, even the most advanced drilling systems would experience energy loss, piston scoring, vibration, and premature wear of internal components.

Key Features and Benefits

1. High-Strength Alloy Construction

Crafted from a premium steel alloy and finished with a precision bronze inner lining, the liner offers both structural rigidity and low-friction performance.

2. Superior Wear Resistance

Through advanced heat treatment and surface hardening, the liner resists deformation and abrasive damage during continuous impact operations.

3. Perfect Dimensional Accuracy

Machined to micrometer tolerances, the liner ensures smooth piston movement and consistent pressure retention under hydraulic load.

4. Optimized Lubrication Channeling

Engineered oil grooves enhance lubrication flow, reducing internal friction and extending part lifespan.

5. Corrosion and Fatigue Resistant

Surface-coated with a protective anti-oxidation layer, the liner remains stable in humid, dusty, and chemically active environments.

6. Improved System Longevity

By maintaining alignment and minimizing shock load transfer, this liner helps prolong the life of the hammer, piston, and cylinder components.
