Accessories For 1838HD+ Rock Drills, Part Number 3115211900, Copper Front Guide Bushing

Precision-Machined Copper Guide Bushing for COP 1838HD+ — Direct OEM Replacement, Zero Fitment Risk

Part No. 3115211900 is a high-performance copper front guide bushing engineered for Atlas Copco / Epiroc COP 1838HD+ rock drills. Installed in the front head assembly, it precisely guides the shank adapter during high-impact drilling — minimizing lateral movement, dampening vibration, and reducing wear on critical internal components.

Made from a proprietary high-strength copper alloy, this bushing delivers inherent self-lubrication and exceptional wear resistance — extending service intervals and maintaining drilling accuracy across demanding underground mining, tunneling jumbo, and quarry applications.

Fully interchangeable with the original, it meets OEM dimensional tolerances and undergoes 100% pre-shipment inspection.

Key Advantages

  • ✅ Exact OEM dimensions — plug-and-play installation with no modifications
  • ✅ Self-lubricating copper alloy reduces friction and eliminates need for frequent re-greasing
  • ✅ Superior wear resistance extends service life by up to 35% vs. standard brass alternatives
  • ✅ Stabilizes shank adapter movement to reduce vibration and improve hole straightness
  • ✅ Protects front head bearings, seals, and hydraulic components from premature wear
  • ✅ Precision-machined to ±0.01 mm tolerance and 100% inspected before shipment

Applications

  • Underground hard-rock mining rigs (e.g., Boomer, Simba)
  • Tunnel boring jumbos with COP 1838HD+ rotation units
  • Quarry blast-hole drilling operations
  • Hydraulic rock drill systems requiring high-cycle reliability
  • Retrofit upgrades for aging COP 1838HD fleets
  • Emergency spare inventory for continuous-operation sites

FAQ

Is this bushing compatible with older COP 1838HD models?
Yes — it’s fully interchangeable with COP 1838HD, COP 1838HD+, and COP 1838ME. All share identical front head geometry and mounting specs.
Does it require special lubrication during installation or operation?
No. The copper alloy has inherent self-lubricating properties — simply clean mating surfaces and install per OEM torque specs. No additional grease needed.
What is the typical lead time for bulk orders (50+ pcs)?
Standard lead time is 5–7 business days. We maintain strategic stock of 3115211900; urgent orders (≤20 pcs) ship within 48 hours.
How does its wear performance compare to original Epiroc parts?
Independent field testing shows equivalent wear resistance and service life — validated via hardness (HB 85–95), tensile strength (≥290 MPa), and microstructure analysis.
Do you provide certification documents (material test reports, RoHS, etc.)?
Yes — all shipments include MTRs (ASTM E8/E29), RoHS/REACH compliance statements, and dimensional inspection reports upon request.
