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

Precision Copper Guide Bushing for COP 1838HD+ — Stable. Wear-Resistant. Direct OEM Replacement.

Part No. 3115211900 is a high-strength copper alloy 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 operation — minimizing lateral movement, dampening vibration, and reducing internal wear. Its self-lubricating properties enhance reliability under heavy-duty conditions, extending both bushing life and overall drill system longevity in underground mining, tunneling jumbos, and quarry applications.

This is a 100% dimensionally and functionally interchangeable OEM-replacement part, manufactured to original tolerances with full pre-shipment inspection.

Key Advantages

  • Exact OEM dimensional match — installs without modification or adjustment
  • High-strength copper alloy with inherent self-lubrication for reduced friction & heat buildup
  • Exceptional wear resistance — extends service life in abrasive mining/tunneling environments
  • Stabilizes shank adapter movement to maintain drilling precision and reduce vibration transmission
  • Protects front head housing and internal components from premature wear and misalignment
  • Precision-machined to ≤±0.01mm tolerance; 100% inspected before shipment

Applications

  • Underground hard-rock mining rigs (e.g., jumbos, bolters)
  • Tunnel boring and development drilling operations
  • Quarry blast-hole and production drilling
  • Hydraulic rock drill systems requiring high-cycle stability
  • Retrofit and maintenance programs for aging COP 1838HD+ fleets
  • Emergency spare parts inventory for continuous drilling operations

FAQ

Is this bushing compatible with older COP 1838HD models?
Yes — it is fully interchangeable with COP 1838HD, COP 1838HD+, and COP 1838ME. All share identical front head geometry and mounting dimensions.
How does the copper alloy compare to steel or bronze alternatives?
Copper alloy offers superior self-lubrication and galling resistance vs. steel, plus higher thermal conductivity and damping than standard bronze — critical for sustained high-RPM drilling.
What is the typical lead time for bulk orders?
Standard lead time is 3–5 business days for quantities ≤50 pcs; larger orders (100+ pcs) ship within 10–14 days — expedited options available upon request.
Do you provide certification or material test reports?
Yes — each batch includes a Certificate of Conformance (CoC) and optional Mill Test Report (MTR) per EN 10204 3.1 upon order confirmation.
