Mining Machinery Parts 3128324624 Epiroc 3128 3246 24 Sliding Piece Atlas Copco drilling rigs parts

The little part that keeps your hammer cycling all shift

The Epiroc 3128324624 sliding piece goes between the hammer piston and the shank adapter on a Cop 1838AW+ rock drill. It’s why impact energy transfers smoothly instead of turning into heat, chatter, and premature wear. At just 0.077 kg, it may look small, but when it scores or flats out, you feel it in lost penetration rate and harder hits on the front end. This is the same part Atlas Copco installs from the factory — same material spec, same heat treatment, same fit. If you run Boomer K111, M1d, or S2 jumbos underground, keeping a spare on the shelf saves you from waiting on air freight when a shift goes sideways.

FAQ
Will this sliding piece fit my K111, or do I need to check the rock drill model?
If your K111 is running a Cop 1838AW+ hammer, it’s a direct match. A few older K111 rigs were retrofitted with different hammers. Send us the serial number off the rock drill nameplate, and we’ll double-check before you order.
Is this an aftermarket part or genuine Epiroc?
It’s genuine Epiroc — we don’t substitute with generic copies. Comes in Epiroc packaging, traceable to the OEM supply chain.
How fast can you ship to a mine site?
We keep this part on the shelf. Most orders go out the same day if placed by early afternoon. Air freight to North America, Australia, and Europe typically lands in 3–5 business days. Express options available if a rig is down.
What tells me the sliding piece is done?
Look for scuffing on the sliding faces, uneven wear that creates step marks, or a drop in impact pressure at the bit. If your drifter sounds harsher than usual or penetration slows at normal feed pressure, pull it and measure the clearance against the spec in the Cop 1838 manual.
I run a fleet of S2 rigs. Can you handle regular bulk orders?
Definitely. We supply contractors and rebuild shops with scheduled deliveries. Give us your annual consumption numbers, and we’ll put together a stock program that avoids downtime and lowers piece-part cost.
