3128303930 SLIDING PIECE ATLAS COPCO

3128 3039 30 Sliding Piece for Atlas Copco Drifters

The 3128303930 SLIDING PIECE ATLAS COPCO (also referenced as 3128 3039 30) is an advanced wear-resistant guiding component engineered for high-frequency rock drilling systems used across multiple Atlas Copco hydraulic drifter platforms. As a critical interface element within the drifter’s internal motion path, the sliding piece ensures smooth, controlled, and low-friction movement of internal components under high impact, continuous vibration, and intense operating pressure.

Manufactured with precision-molded, high-density polymer materials and reinforced geometric profiles, the 3128303930 SLIDING PIECE ATLAS COPCO delivers exceptional abrasion resistance, optimized sliding dynamics, and long service life in underground mining, quarry drilling, tunneling, and high-tonnage excavation environments.

Supplied exclusively by 3GEN Export, the part meets strict dimensional and performance standards, ensuring seamless compatibility with Atlas Copco drilling systems worldwide. 3GEN Export provides global delivery to over 100 countries in just 5 working days, enabling uninterrupted machine productivity for drilling operators and contractors.

Function and Purpose of the 3128303930 Sliding Piece Atlas Copco

The 3128303930 SLIDING PIECE ATLAS COPCO functions as a stabilizing and guiding insert within the drifter assembly, typically positioned along the hammer or piston movement channel. Its purpose is to:

• Maintain correct axial alignment between piston, chuck, and front head

• Absorb frictional loads during high-speed reciprocation

• Reduce wear on metallic components via a controlled sliding surface

• Ensure consistent drilling trajectory and energy transfer

• Minimize heat generation through optimized polymer-based friction properties

In hydraulic drifters, where impact forces exceed thousands of blows per minute, the 3128 3039 30 sliding piece plays an essential reliability role by preventing internal misalignment, reducing vibration, and extending the lifespan of hammers, bushings, seals, and sleeves.
