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.
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.
Key Features and Performance Advantages
High-Resistance Polymer Engineering
The 3128303930 SLIDING PIECE ATLAS COPCO is molded from industrial-grade, impact-modifying polymers, offering:
Exceptional resistance to cracking and fatigue
Superior heat distribution during long drilling cycles
Self-lubricating characteristics that reduce friction coefficients
Optimized Wear Geometry
The sliding piece integrates structural ribs and precision-profiled faces that help:
Maintain stable axial motion
Improve impact load distribution
Prevent jamming or uneven wear within the sliding channel
Dimensional Accuracy for Perfect Fit
With tight manufacturing tolerances and a controlled thickness ratio, the sliding piece ensures:
Zero-modification installation
Perfect fit within Atlas Copco drifter cavities
Fully stabilized piston guidance
Extended Maintenance Intervals
Using high-durability polymers significantly reduces the frequency of:
Chamber cleaning
Internal drifter rebuilds
Part replacements
The result is increased uptime for heavy-duty drilling operations.
Corrosion-Free Performance
Unlike steel components, this polymer sliding piece:
Does not oxidize
Maintains consistent performance in wet, humid, or chemical-heavy environments
