Overview

The 3115 2124 00 GUIDE ATLAS COPCO is an internal guiding component located in the drifter assembly of Atlas Copco rock drills. Its main function is to center the piston, absorb lateral loads, and minimize vibration inside the hammer housing.

This component is critical for maintaining the correct clearance between the piston and the cylinder bore. Without the proper guide, the piston can experience misalignment, leading to performance loss, increased wear, and reduced efficiency in impact delivery.

The guide works continuously in high-pressure hydraulic systems that deliver thousands of blows per minute, requiring exceptional strength, oil compatibility, and thermal stability.

Role in Rock Drill Systems

The 3115 2124 00 GUIDE ATLAS COPCO acts as a piston stabilizer within the drifter. It ensures the piston’s axial motion remains perfectly aligned, allowing each hydraulic impact to be transmitted directly to the shank adapter.

By reducing metal-to-metal contact, this guide minimizes vibration, prevents galling, and keeps the drifter interior free from scoring. Its bronze alloy structure provides an ideal balance of strength, elasticity, and self-lubricating properties.

A misaligned or worn guide can drastically affect performance—reducing impact energy, increasing oil consumption, and potentially damaging expensive internal components such as the piston and front bushing.

Material and Engineering Design

Phosphor-Bronze Composition

Crafted from high-density phosphor-bronze, the 3115 2124 00 GUIDE ATLAS COPCO offers superior friction resistance and natural lubricity. This alloy combines copper, tin, and phosphorus to create a material that withstands continuous impact and sliding wear.

Precision Machining

Each guide is CNC-machined to micrometer tolerances, ensuring a perfect fit inside the drifter housing. The internal bore is finished with a mirror-smooth surface to maintain consistent lubrication film and minimize energy loss due to friction.

Structural Strength

Despite weighing just 1.35 kg, the component endures radial pressures exceeding 120 MPa. Its dimensional stability under thermal expansion prevents misalignment even when operating temperatures rise during extended drilling cycles.

---

Compatibility

The 3115 2124 00 GUIDE ATLAS COPCO is compatible with several Atlas Copco drifters and hydraulic rock drills, including but not limited to:

• Atlas Copco COP 1238 series

• Atlas Copco COP 1838 series

• Atlas Copco COP 2238 series

• Atlas Copco COP 3038 series

• Atlas Copco ROC F7 and ROC F9 drilling rigs

• Atlas Copco Boomer T1D, T2D and L2D underground drills

• Atlas Copco Hydraulic Power Pack assemblies

Each of these models relies on piston precision and hydraulic balance. The 3115 2124 00 GUIDE ATLAS COPCOensures consistent alignment and smooth reciprocating motion, allowing the hammer to deliver its full rated impact power.

Mechanical Advantages

• Improved Piston Stability: Centers the piston to prevent side loading.

• Extended Component Life: Protects bushings, pistons, and liners from scoring.

• Superior Lubrication: Maintains hydraulic-oil film at all times.

• Vibration Reduction: Dampens internal oscillations and mechanical stress.

• Operational Efficiency: Ensures consistent impact energy transmission.

These advantages make it one of the most critical wear-resistant components in the entire drifter assembly.

Installation and Maintenance

Installation Steps

1. Clean the drifter housing and remove any metal debris.

2. Lightly lubricate the guide’s outer surface with hydraulic oil.

3. Insert carefully into the housing bore using a press tool.

4. Verify axial alignment with a gauge to confirm concentricity.

Maintenance

• Inspect during every major overhaul or after 1 000 operating hours.

• Replace if radial clearance exceeds 0.2 mm.

• Use only compatible hydraulic oils to preserve surface film integrity.

Routine inspection ensures the guide continues to deliver consistent performance and prevents unexpected downtime.

Operating Environment

The 3115 2124 00 GUIDE ATLAS COPCO is designed for heavy-impact rock-drilling conditions:

• Ambient temperature range: –35 °C to +200 °C

• High vibration resistance (> 60 Hz continuous operation)

• Hydraulic pressure compatibility up to 250 bar

• Resistance to abrasive dust and moisture

Its bronze construction makes it naturally corrosion-resistant, even when exposed to water or rock dust during underground or surface drilling.

Why Bronze Matters

Bronze’s microstructure provides excellent seizure resistance when metal components operate under boundary-lubrication conditions. In a rock drill where thousands of rapid impacts occur each minute, this property prevents micro-welding and galling that could seize the piston.

Additionally, bronze dissipates heat rapidly, protecting the drifter from temperature buildup. These combined properties ensure that the 3115 2124 00 GUIDE ATLAS COPCO maintains dimensional precision across countless duty cycles.

---

Applications in Atlas Copco Systems

This guide is primarily used in hydraulic drifters for:

• Surface drilling rigs used in quarrying and road-construction projects.

• Underground tunneling equipment operating in confined environments.

• Foundation and anchoring rigs requiring precise percussive force.

Its purpose is identical across applications—maintaining mechanical harmony between the moving piston and the stationary drifter body.

---

Weight and Dimensional Efficiency

Weighing approximately 1.35 kg, the 3115 2124 00 GUIDE ATLAS COPCO provides the perfect balance between mass and mechanical stiffness. Its compact geometry minimizes space consumption while maintaining strength, contributing to lower overall machine weight and smoother reciprocation.

---

Replacement Indicators

Operators should consider replacing the guide if any of the following occur:

• Noticeable lateral movement of the piston during operation.

• Reduction in impact power or irregular blow patterns.

• Metallic scraping noises from the drifter housing.

• Measured clearance between piston and guide > 0.2 mm.

Replacing worn guides on schedule helps protect expensive components and reduces overall maintenance costs.
