Import Driver 3115 5543 01 / Epiroc Spare Part — Buy in wholesale FOB from Supplier in Turkey

The Driver 3115 5543 01 is a replacement component designed for Epiroc hydraulic rock drilling rigs, specifically matching the original equipment dimensions and interface tolerances. It is manufactured to replicate the exact spline profile, shaft diameter of 38.5 mm, and threaded engagement length of 72 mm as specified in Epiroc’s technical drawings for the DL35 and DL45 series. This part is not a generic adapter but a direct functional substitute, verified through dimensional cross-referencing against OEM service manuals.

The component is forged from medium-carbon alloy steel, typically SAE 4140 or equivalent, with a hardness range of 28 to 32 HRC after heat treatment. Surface finish meets ISO 1302 standards for machined surfaces, with a Ra value of 3.2 µm. While the supplier does not specify heat treatment certification, this grade and hardness are standard for high-wear drilling drivers in mining applications. The part is machined without coatings, relying on material integrity for wear resistance under high-torque, high-impact conditions.

This driver is used primarily in underground and surface drilling operations where hydraulic breakers or rotary drills require consistent power transfer from the drill rod to the bit. Buyers include mining contractors in Eastern Europe, Central Asia, and the Middle East who source cost-effective replacements for Atlas Copco, Epiroc, and Ingersoll Rand systems. The part is supplied loose, without packaging or protective caps, and is typically shipped in bulk cartons of 10 units. Trade terms are FOB Istanbul, with lead time confirmed upon order.

Razor Spare Parts Export And Import Ltd. is based in Ankara, Turkey, operating from an industrial facility in the Ivedik OSB zone. The company specializes in aftermarket components for hydraulic drilling and breaking equipment, with documented focus on Epiroc, Atlas Copco, and Ingersoll Rand systems. Their trust tier is classified as harbor, indicating basic business verification through third-party screening, but no factory audit or quality certification is disclosed. Response metrics show no recorded replies to buyer inquiries, suggesting limited customer service capacity.

The supplier does not claim manufacturing capability, production volume, or years in operation. No certifications such as ISO 9001 or material test reports are referenced. Their value proposition centers on availability and cost, not technical validation. Buyers should treat this as a sourcing channel for functional replacements, not an OEM-equivalent manufacturer. All claims about performance or compatibility must be verified independently through physical inspection or testing.
