Atlas Copco SLIDING PIECE 3128228755 Epiroc 3128 2287 55 DRILLING RIGS Boltec 235h Boltec Lc

The sliding piece your COP 1838 drifter was built for

Part number 3128228755 is the factory sliding piece for Atlas Copco and Epiroc COP 1838 series drifters. It's a polymer-composite wear part that guides the piston accurately, cycle after cycle. The material handles heat and friction without softening, which helps keep vibration low and alignment stable inside the rock drill.

If your Boltec 235, 235h, Lc, or Md rig has started eating shanks or losing percussion power, a worn sliding piece is often the culprit. Swapping in this OEM unit gets the drifter back to spec without any modification. We hold stock and ship worldwide, so you're not waiting weeks for a box to clear customs.

Highlights
Key Advantages
  • Same part Atlas Copco bolts into new COP 1838AW+ drifters – no aftermarket guesswork.
  • Polymer composite body takes heat and side load without deforming, so alignment stays tight.
  • Cuts down vibration transfer to the front guide and shank, which extends shank life.
  • Drop-in fit for Boltec 235, 235h, Lc, and Md – pull the old one out, push this one in.
  • In stock in multiple regions, with traceable batch numbers and full factory warranty.
Use Cases
Applications
  • Boltec 235 and 235h bolting rigs in underground hard rock mines.
  • Boltec Lc and Md jumbos running COP 1838 series rock drills.
  • COP 1838AW+ hydraulic drifters – replaces worn sliding pieces during scheduled service.
  • High-cycle drifter rebuilds where vibration and wear have become noticeable.
  • Tunnel construction sites that stock OEM wear parts to minimize downtime.

FAQ
FAQ
How do I know this is a genuine Epiroc part and not a copy?
It comes in Atlas Copco/Epiroc OEM packaging with batch-level traceability. The material compound and dimensional tolerances match the factory drawing for COP 1838AW+ drifters – you won't get that with pattern parts.
Will this fit my rig if it's an older Boltec model?
If your rig uses a COP 1838 series drifter, yes. It's a direct fit for Boltec 235, 235h, Lc, and Md machines. Double-check the drifter ID plate if you're unsure – contact us and we'll help you confirm.
What happens if I keep running a worn sliding piece?
The piston starts to wander, which hammers the front guide and shank adapter. You'll see faster shank wear, dropped percussion efficiency, and eventually damage to the cylinder bore. The sliding piece is cheap insurance compared to a full front-end rebuild.
What's your actual lead time to a mine site in West Africa or South America?
Most orders ship same day if we have stock in your region. Express freight usually lands at major mining hubs in 3–7 business days. We can quote exact delivery times once we have your location.
Do you guys stand behind this part with any warranty?
Since it's an OEM part, it's covered by the standard factory warranty for material and manufacturing defects. We handle claims directly with the manufacturer so you don't get bounced around.
