3115028800 液压重型活塞备件，用于钻机 Epirco 3115 0288 00

A piston that matches the OEM number and holds up underground.

The 3115028800 hydraulic piston is a drop-in replacement for Epirco 3115 0288 00 rock drills and similar mining equipment. It's machined from a forged carbon steel blank — a material choice that gives it better grain structure and higher fatigue strength than ordinary bar stock. That means fewer stress cracks, longer intervals between rebuilds, and more run hours on the job.

  • Material: Forged carbon steel, picked for its resistance to galling and impact in high-cycle hydraulic circuits.
  • Fit: Built to the OEM dimensions for Epirco 3115 0288 00 — swap the old one out, drop this one in.
  • Wear life: Surface hardness and finish matched to the original spec so seals seat properly and leaks don't start early.
  • Where it's used: Hydraulic drifters, rock drills, and breaker attachments in hard rock mining and tunneling.

Highlights
Key Advantages
  • Forged from carbon steel — gets you away from premature fatigue failures that can show up with cast or bar-stock pistons.
  • Surface finish controlled for a proper seal interface, cutting down on bypass leakage and keeping cylinder efficiency up.
  • Same dims as Epirco 3115 0288 00 — no filing, shimming, or re-machining just to make it fit.
  • Tested under cycling loads above typical mining circuit pressures so it doesn't fold when the system spikes.
  • Hardness profile balanced between wear resistance and shock absorption: hard enough to last, tough enough not to chip.
Use Cases
Applications
  • Hydraulic drifters and rock drills in underground hard rock mining
  • Rotary drill rigs for surface mining where sustained pressure holds are common
  • Hydraulic breakers and hammers in quarry face operations
  • Tunnel boring machine auxiliary hydraulic systems
  • Exploration drill rigs that run long shifts with minimal downtime

FAQ
FAQ
Does the 3115028800 piston drop straight into an Epirco 3115 0288 00 drill without rework?
It's built to the OEM print, so the short answer is yes. Mounting dimensions, seal grooves, and overall length are all matched. In most cases it's a same-day swap — pull the old piston, inspect the cylinder bore, fit this one, and torque it down.
How does the forged carbon steel hold up compared to an OEM piston?
Forged carbon steel typically has better fatigue resistance than cast iron or lower-grade steels seen in some budget parts. The grain flow follows the piston shape, which helps it survive pressure cycles that crack materials with random grain structure. Customers generally see similar life to the original, provided the hydraulic oil is kept clean.
What's a realistic lead time for these, and do you keep buffer stock?
We hold stock on this part number in our main warehouse. For orders under 10 pieces, it usually ships within 2-4 working days. Larger batches might need a production slot — typically 10-15 days on the water. Express freight can cut transit times by half if a rig is down.
Can you supply the seal kit or other soft parts that go with this piston?
Right now we focus on the hard parts. But we can point you to reliable seal suppliers that match the OEM groove geometry. If you need a full rebuild kit, let us know and we'll check what we can source alongside the piston.
What inspection steps do you run before it leaves the factory?
Each piston gets a dimensional check against the OEM drawing (OD, length, groove positions, surface finish), a Rockwell hardness test spot, and a visual check for surface defects. We keep records by batch number so you can trace back if needed.
