Drilling Rig Parts 3115534020 Stop Ring Piston Cop 1838HD+ Epiroc 3115 5340 20 Atlas Copco 2kg

Hardened Stop Ring for Atlas Copco 1838HD+ Rock Drills

The 3115534020 stop ring is a factory Epiroc part that keeps your Atlas Copco 1838HD+ piston cop running within stroke spec. It’s machined from hardened steel, weighs 2 kg, and bolts straight in without rework. You get the same ring that ships with the OEM assembly — no pattern copy, no fitment guesswork. It holds piston alignment under hard percussion loads, so the hammer doesn’t overtravel and beat up adjacent parts. Also listed as Epiroc 3115 5340 20.

  • Factory Epiroc / Atlas Copco stop ring, not aftermarket
  • Drop-in fit for 1838HD+ piston cop housings
  • Hardened steel, 2 kg — handles repeated impact without mushrooming
  • Ships from stock; same-day dispatch on orders placed before 2 PM UTC

Highlights
Key Advantages
  • Factory Epiroc stop ring — part 3115534020, also stamped 3115 5340 20
  • Machined to OE tolerances so the piston cop holds stroke length under load
  • 2 kg hardened steel ring; won’t deform after weeks of multi‑shift hammering
  • Stops piston overtravel that chews up seals, guide bushes, and the front head
Use Cases
Applications
  • Atlas Copco 1838HD+ drifters running in surface or underground benches
  • Heavy percussion work — granite, quartzite, hard sandstone
  • Mine‑site rebuilds and mid‑life piston cop overhauls
  • Tunneling jumbos that see 16+ hours of hammer time a day
  • Quarry rigs that cycle the piston cop hard in blast‑hole drilling

FAQ
FAQ
Is this an original Epiroc part, or will I get a pattern ring?
It’s the genuine Epiroc ring, part number 3115534020. Same as the one cross-listed under 3115 5340 20 for older Atlas Copco catalogs. If you need batch photos or batch traceability before payment, just ask.
Does this stop ring fit other drifters, or only the 1838HD+?
It’s machined specifically for the 1838HD+ piston cop bore. If you’re swapping it into a different housing, measure your existing ring’s OD and thickness first. We can cross‑check dimensions if you send the numbers.
What’s the lead time if I order today?
Stock sits on the shelf in Dubai. Orders confirmed before 2 PM UTC go out the same day. Transit is 3–7 working days with DHL, depending on your import clearance. LCL freight to port options available for bulk orders.
How do I confirm the part number without tearing down the drifter?
Check your rig’s parts manual, or pull the piston cop assembly drawing. The stop ring sits right behind the front guide. If you only have the machine serial number, email it over and we’ll pull the correct drawing for you.
What if the ring fails early?
We cover manufacturing defects under a standard 12‑month warranty. That means cracks from internal material flaws, not normal wear or rock-scour damage. Keep the ring properly greased and it should last a full piston‑change interval.
