3115183300 冲击活塞后导向套 COP 2238HD+ Epiroc 3115 1833 00 Atlas Copco 凿岩机配件

Cuts drill steel wear, not corners

The 3115183300 rear guide bush is what sits behind the piston on COP 2238HD+, COP 1440, and COP 1838 drifters. It’s a genuine Epiroc part, so the tolerances, heat treatment, and lubrication pathways match the rest of the front end. On a dual-damping rig, that geometry helps drop steel wear by roughly 35%—fewer cracked rods, fewer changeouts, less downtime when you’re 600 meters down a drift.

Highlights
Key Advantages
  • Straight OEM replacement for Epiroc 3115183300 – drops into COP 2238HD+, COP 1440, and COP 1838 without filing, shimming, or rework
  • Works with the dual damping system to cut impact stress on drill steel; we typically see 30–35% longer life on rods and shanks in granite and hard schist
  • Internal lubrication paths are machined to factory spec, so oil gets where it’s needed and the bush runs cool even under 22 kW percussion load
  • Hardened alloy steel with ground contact surfaces – handles the side loads from 38–76 mm hole ranges without picking up or fretting the bore
Use Cases
Applications
  • Underground drifting and tunneling in hard rock – the bush lives right behind the piston where shock loads peak
  • Quarry and blast-hole drilling with COP HD+ drifters on 38–76 mm holes
  • Civil works and deep foundation drilling that run COP 1440 or 1838 on a rig or wagon drill
  • Preventative maintenance swaps on older COP 2238 / 2238HD machines where front-end wear is starting to show
  • Workshop rebuilds – pair it with a fresh piston and sealing kit to bring the front guide assembly back to factory clearance

FAQ
FAQ
Does 3115183300 fit all COP 2238 variants?
It fits COP 2238HD+ and COP 2238HD straight out of the box. It’s also backward-compatible with COP 2238, COP 1838, and COP 1440 drifters. Check your parts book if you’re running a very early serial number, but 99% of the time it’s a direct swap.
How do I know it’s a real Epiroc part and not a copy?
Every genuine 3115183300 bush comes in Epiroc/Atlas Copco packaging with laser-etched part numbers. It’ll have the same surface finish and chamfer details as the one you’re pulling out. We don’t deal in aftermarket copies.
What wears first on this guide bush?
Usually the ID where the piston tail runs, or the face that butts against the damper. If you’re seeing ridging deeper than 0.15 mm or polished bands wider than 15 mm, it’s time to replace it before it starts chewing up the piston.
Do I need a press to install it?
Typically no. On most COP front assemblies the bush is a slip fit in the housing once you’ve removed the retaining ring. A light tap with a brass drift is often enough. If it binds, stop and check for burrs in the bore.
How often should this bush be inspected?
Every 500 percussion hours or during your regular PM cycle, whichever comes first. Pull the retaining ring, slide it out, and measure the ID with a bore gauge. Keep the lube holes clear – those tiny ports clog easier than you’d think.
