Highlights
Key Advantages
  • Drops straight into COP1838 drifters with no messing around—machined to match factory dimensions, so alignment stays true under load.
  • Composite material fights abrasive dust and moisture underground, stretching the time between slide changes compared to softer alternatives we’ve pulled from rigs.
  • Takes the beating so your piston and bushings don’t: when this piece wears, you swap a 0.6 kg part instead of opening the whole drifter for a major rebuild.
  • Guide surfaces stay dimensionally stable across the temp swings you get deep in a heading, which means consistent feed pressure and fewer surprises mid-round.
Use Cases
Applications
  • Face drilling with Boomer 282 and 281 fleets in development headings
  • Rock bolting cycles on Boltec 235h and Boltec LC/MD rigs
  • Long-hole production drilling with Simba S7d in sublevel stopes
  • Quarry and construction drilling on Roc L8, D9, and T-series surface rigs

3128307488 SLIDING PIECE ATLAS COPCO
3128 3074 88 SLIDING PIECE ATLAS COPCO
The 3128307488 SLIDING PIECE ATLAS COPCO (also referenced as 3128 3074 88) is a precision-engineered wear component designed to support the smooth mechanical guidance of critical moving assemblies within Atlas Copco hydraulic drifters. Manufactured for extreme impact environments, this sliding piece ensures controlled movement, reduced friction, predictable wear behavior, and long-term drilling performance in demanding rock drilling operations.

Supplied globally by 3GEN Export, this component is engineered to meet high-load industrial requirements and withstand the harsh vibration, dust, and impact dynamics of underground mining, tunneling, quarrying, and construction drilling applications. With OEM-grade geometry and optimized material behavior, the 3128307488 SLIDING PIECE ATLAS COPCO maintains alignment accuracy and stabilizes internal motion within the drifter carriage.

This long-form technical description is written to assist maintenance teams, procurement departments, drilling contractors, and heavy-equipment fleet managers in fully understanding the mechanical role, compatibility, performance advantages, and global supply options for this specialized wear part.

What Is the 3128307488 Sliding Piece Used For?
The 3128307488 SLIDING PIECE ATLAS COPCO serves as a stabilizing and guiding interface within the sliding assemblies of Atlas Copco hydraulic drifters. It prevents metal-to-metal contact inside the feed mechanism and ensures that the drifter piston travels smoothly within the hammer housing.

Sliding pieces are mission-critical in maintaining:

Straight, linear motion paths

Reduced internal vibration

Controlled movement during impact cycles

Precision alignment during high-frequency hammering

Protection of neighboring components from accelerated wear

When a sliding piece becomes worn, it introduces instability to the drifter, often causing:

Excessive vibration

Loss of drilling accuracy

Irregular feed pressure

Noise increases

Uneven wear on bushings and pistons

Replacing the sliding piece with a high-quality OEM-equivalent component like 3128 3074 88 restores the drifter’s original mechanical stability and drilling performance.

Compatibility – Which Atlas Copco Models Use 3128307488?
The 3128307488 / 3128 3074 88 SLIDING PIECE is commonly used in mid-range Atlas Copco hydraulic drifters built for drilling systems in underground mining and tunneling.

Compatible models typically include (depending on drilling rig configuration):

COP 1838

COP 1838ME

COP 1838HD

COP 1838HR

COP 1838+: Field variants

Boomer M2 / M2C / M2D rigs equipped with COP1838-class drifters

Rocket Boomer rigs using the COP1838 series

Note: Compatibility may vary slightly depending on rig year, configuration, and rebuild variant. Customers often verify the component against their drifter’s serial number during procurement.

3GEN Export provides fast assistance for compatibility checks before order processing.

Technical Features of the 3128307488 Sliding Piece
The sliding piece is engineered with a specialized composite material blend formulated for:

Low friction coefficient

High surface strength

Resistance to dust abrasion

Impact tolerance

Controlled wear pattern

Stable expansion behavior under heat

Its geometry includes:

Precision-machined guide surfaces

Dimensional consistency for accurate alignment

Reinforced step-design for steady load distribution

Lightweight construction

Noise-reducing material composition

These features ensure consistent drifter operation even under repetitive percussion cycles and extreme drilling stress.

Mechanical Role Inside the Drifter
1. Guiding Function
The sliding piece functions as the guiding backbone, allowing the piston and carriage system to move linearly without deviation.

2. Stability and Load Distribution
It absorbs and redistributes mechanical load across the drifter housing, minimizing localized stress.

3. Wear Management
Instead of surrounding metal components wearing prematurely, the sliding piece acts as the sacrificial wear component, which can be replaced during maintenance intervals.

4. Vibration Damping
Its material composition reduces high-frequency vibration and noise during drilling.

5. Protection for Internal Components
Prevents galling, scoring, and deformation inside the drifter mechanism.

Why the Sliding Piece Must Be Replaced Regularly
In hydraulic drifters, sliding pieces experience continuous friction, impact resonance, and thermal cycling. Over time, this results in:

Surface erosion

Micro-fractures

Loss of thickness

Uneven wear marks

Feeding irregularities

When these symptoms appear, replacing the sliding piece ensures:

Consistent drilling force

Prolonged lifespan of pistons and bushings

Lower lubrication consumption

Reduced downtime

Restoration of drilling accuracy

Weight of 3128307488 Sliding Piece
The typical weight of the 3128307488 / 3128 3074 88 SLIDING PIECE ATLAS COPCO is:

≈ 0.62 KG

(Slight variation may occur depending on manufacturing batch.)

FAQ
FAQ
Will this slide fit my Boomer 282 if it’s an older rebuild?
If your 282 is running a COP1838-class drifter—which most do—then yes. We always suggest grabbing the drifter serial number before you order. That way we can double-check the variant and make sure you’re not dealing with a field mod that changed the slide specs.
What actually happens when the sliding piece wears down too far?
You’ll feel it first: rougher feed, more vibration through the controls, and the drill starts wandering off target. Inside, the piston loses its straight guide, so it starts hammering unevenly on the bushings. Leave it too long and you’re looking at scoring in the housing—that turns a quick slide swap into a bench job.
How does this composite hold up in wet, muddy conditions?
We’ve sold these into very wet underground headings and wet quarries. The composite doesn’t swell or soften like some nylon-based copies, so dimensional stability holds. Still, muddy water is abrasive; check the slide during your normal pm cycle and keep the lube circuit clean.
Are these slides balanced to OEM weight?
They’re manufactured to match the 0.62 kg spec. A slide that’s too heavy or too light will change the drifter’s dynamic balance, especially at high percussion rates. We keep them within tight tolerances to avoid adding nuisance vibration to the rig.
Can I order a trial piece before committing to a fleet-wide order?
Happens all the time. Ask for a sample order—we’ll ship one out, you run it through a couple of rounds, and if it does the job we’ll set you up with bulk pricing and scheduled deliveries.
