3115554300, 3115 5543 00 DRIVER ATLAS COPCO

When a rock drill drifter is working at full load, the most unforgiving stress usually isn’t the obvious one. It’s the repeated micro-impacts, the torsional pulses, and the constant misalignment corrections happening thousands of times per shift. That’s exactly where 3115554300, 3115 5543 00 DRIVER ATLAS COPCO earns its keep: it acts as a precision “interface” component that helps transmit rotation, maintain concentric alignment, and absorb wear in the coupling zone of the drifter assembly.

From the images, this part is a robust, cylindrical driver element with an internal profile designed to engage a mating component (commonly a splined or keyed interface). In practical field terms, it is the kind of part that keeps power transfer clean and predictable, so the drill string responds instantly to torque and impact without slop, chatter, or accelerated wear elsewhere.

At 3GEN Export, we supply 3115554300 / 3115 5543 00 DRIVER ATLAS COPCO as an OEM-supplier alternative built for demanding rock drilling duty, and we ship worldwide in 5 working days.

What the 3115554300 / 3115 5543 00 Driver actually does

In many Atlas Copco / Epiroc drifter layouts, a “driver” sits in a high-load path where torque and axial forces meet. The goal is simple: transfer force efficiently while sacrificing itself (as a wear-managed element) before more expensive assemblies take damage.

Torque transfer without backlash

In hard rock drilling, backlash is not a small issue, it becomes heat, vibration, and broken components. 3115 5543 00 DRIVER ATLAS COPCO helps keep the torque handoff tight so the drifter’s rotation system can do its job with minimal lag, especially during collaring, reaming, and fracture zones.

Alignment support under vibration

Even when the machine is “set,” the drilling axis is never perfectly stable. Ground conditions, feed force changes, and bit interaction create constant micro-misalignment. A properly machined 3115554300 driver supports alignment and reduces uneven contact loading, one of the fastest routes to premature wear.

Wear management where it matters

This component is designed to work in a friction and load environment. Instead of letting wear attack critical mating parts, 3115 5543 00 DRIVER ATLAS COPCO takes the brunt of contact stress and can be replaced during planned service.

Typical application areas in the drifter assembly

Depending on the exact drifter configuration, 3115554300, 3115 5543 00 DRIVER ATLAS COPCO is commonly associated with the rotation/drive interface region, where the system must deliver torque consistently while the percussion system continues cycling.

What this means for you operationally:

• You’ll see performance impact when the driver begins to wear (rotation feel becomes “soft,” heat increases, or vibration patterns change).

• Replacement restores the crisp, controlled response that operators recognize immediately.

• It’s a cost-efficient “control point” in preventive maintenance.

Compatibility: Which ATLAS COPCO / Epiroc models use this part?

Public vendor listings commonly associate 3115554300 / 3115 5543 00 DRIVER ATLAS COPCO with drifter families used across multiple underground and surface drill rigs. One listing describes it as a driver for a COP 2560EX+ context.

In a broader machine list, the same part number is shown in contexts that include well-known Atlas Copco / Epiroc rigs such as Rocket Boomer and other drilling platforms.

Because Atlas Copco/Epiroc fleets vary by region and retrofit history, the most reliable fitment method is:

• Confirm drifter model (e.g., COP series) and serial range

• Confirm the mating interface (internal profile, length, lubrication features)

• Match the part number 3115554300 or formatted variant 3115 5543 00

Common equipment families where you may encounter it

Based on the way these parts are typically deployed, 3115 5543 00 DRIVER ATLAS COPCO may appear in drifter-driven rigs used for:

• Underground development drilling

• Production drilling

• Tunneling and bolting-related drilling packages

• Certain surface drilling configurations where COP drifters are used

If you share the machine model + drifter model (or a BOM screenshot), we can confirm fitment quickly before shipment.

Material and build logic (what you should expect)

From the images, the component appears to be manufactured from a wear-oriented alloy with a smooth external surface and a precisely machined internal driving profile. In rock-drill duty, that typically means:

Wear-focused alloy selection

A driver is chosen for predictable wear behavior and stable performance under lubrication. The correct alloy helps:

• Reduce galling risk under boundary lubrication

• Handle repetitive vibration without cracking

• Maintain dimensional stability under heat

Precision machining of the internal interface

The internal geometry is the heart of the part. The machining quality determines:

• Torque transfer quality

• Contact stress distribution

• Service life consistency

With 3115554300, 3115 5543 00 DRIVER ATLAS COPCO, the internal profile must match perfectly, small deviations can cause fretting, localized scoring, and rapid heat rise.

Practical technical checkpoints (field-friendly)

Exact dimensions depend on the drifter family and revision, so instead of guessing numbers, here are the checks that matter most when verifying 3115 5543 00 DRIVER ATLAS COPCO against your removed part:

Dimensional checks

• Overall length (end-to-end)

• Outer diameter and seating surfaces

• Internal profile geometry (spline/key form) and depth

• Chamfers/lead-in geometry (helps assembly and prevents edge chipping)

Lubrication and oil features

• Any lubrication holes/ports (location and diameter)

• Any internal lubrication channels or grooves

• Surface finish at contact zones (too rough increases heat; too smooth can reduce oil retention)

Fit and seating behavior

• Press-fit or slip-fit zones (depending on design)

• Evidence of rotation in a stationary seat (a sign of incorrect fit or worn retention)

If you can provide one measurement (overall length) and a close-up of the internal profile, it becomes even easier to validate 3115554300 before dispatch.

Symptoms of a worn driver (what operators notice first)

A driver usually “announces” wear through behavior changes:

Early-stage wear

• Slight loss of crisp torque response

• Minor vibration increase during rotation under load

• Unusual polish marks or light fretting dust near interface areas

Mid-stage wear

• Noticeable heat rise around the drive interface

• Rotation feels inconsistent (especially in harder strata)

• Lubrication becomes darker faster (metal contamination)

Late-stage wear (replace immediately)

• Chatter, knocking, or sudden torque spikes

• Visible deformation on internal profile edges

• Rapid wear on the mating component (bad sign, cost escalates quickly)

Replacing 3115 5543 00 DRIVER ATLAS COPCO at the early-to-mid stage is usually the sweet spot: it protects higher-value assemblies and keeps drilling consistency.

Installation guidance (service-bay level, not generic)

Below is a practical approach used by many field techs. Always follow your site safety rules and the machine’s service manual.

Preparation

• Clean the area thoroughly (dust + oil = abrasive paste)

• Inspect mating components for burrs, scoring, or edge rollover

• Verify the removed part number and compare with 3115554300 / 3115 5543 00

Installation steps (typical best practice)

1. Confirm orientation (lead-in chamfer side and any port alignment)

2. Apply the correct lubricant (per your drifter’s lubrication system spec)

3. Seat the part evenly, avoid cocking during insertion

4. Verify smooth engagement with the mating profile (no forced rotation)

5. Check for correct retention and alignment before full reassembly

Post-install checks

• Run at low load first and monitor noise and heat

• Confirm lubrication delivery is correct

• Re-check for abnormal vibration after initial bedding

A properly installed 3115554300 driver will “feel” smooth and responsive almost immediately.

Estimated weight (KG)

Because exact weight depends on production revision and final machining, the most honest way to state weight is as an expected range.

• Estimated net weight: ~ 4.0 kg

• Estimated shipping weight (with protective packing): ~ 4.7 kg
