Overview

Every mechanical assembly depends on the reliability of its fasteners. The 3115 1041 00 WASHER ATLAS COPCOperforms the vital task of stabilizing joints, distributing pressure evenly, and preventing deformation of contact surfaces under tension.

This washer is used in critical points within Atlas Copco’s drilling systems, such as hydraulic drifter housings, rotation units, and mounting flanges, where precision load control directly affects performance and safety.

Function and Importance

The 3115 1041 00 WASHER ATLAS COPCO acts as a load-spreading interface between the bolt head and the surface beneath it. Without this component, the clamping force from bolts could concentrate in one point, causing uneven stress, surface indentation, or eventual loosening under vibration.

By inserting this washer, Atlas Copco engineers ensure that tightening torque translates into stable and uniform pressure distribution, an essential requirement for maintaining hydraulic-system sealing and frame rigidity.

Engineering Design and Material Composition

High-Tensile Alloy

The washer is produced from hardened carbon steel with uniform grain structure to withstand compression and torsional stress. It resists elongation and surface deformation even under continuous dynamic loading.

Precision Machining

The surfaces of the 3115 1041 00 WASHER ATLAS COPCO are ground to strict tolerances, ensuring consistent thickness across all points. This guarantees even torque application and eliminates assembly misalignment.

Corrosion Protection

Its phosphate + black oxide finish delivers high resistance to corrosion, oxidation, and hydraulic-fluid exposure, an important feature for drilling environments involving moisture, dust, and vibration.

---

Performance Advantages

• Ensures even torque distribution across fastened joints.

• Protects assembly surfaces from damage and wear.

• Prevents bolt loosening in high-vibration applications.

• Extends the life of critical components by maintaining structural alignment.

• Compatible with both hydraulic and pneumatic assemblies.

The 3115 1041 00 WASHER ATLAS COPCO guarantees the mechanical integrity that keeps drilling rigs operating safely and efficiently.

Applications and Compatibility

Compatible Atlas Copco Models

This washer fits multiple drilling and hydraulic systems, including:

• Atlas Copco COP 1838 and COP 2238 drifters

• Atlas Copco ROC D7 and ROC F9 surface drilling rigs

• Atlas Copco Boomer T1D and T2D series

• Atlas Copco L7 and L8 hydraulic units

• Atlas Copco ROC L8 crawler drills

• Atlas Copco Hydraulic Breaker Assemblies

Because of its standardized dimensions and hardness, it can also be applied to other industrial systems requiring 14 mm fastener assemblies.

Installation Guidelines

1. Inspect the bolt and surface for debris or wear.

2. Place the washer flat between the mating surface and the bolt head.

3. Tighten to the manufacturer’s torque specification using a calibrated wrench.

4. Re-check torque after the first operating cycle to compensate for thermal expansion.

Correct installation ensures optimal clamping and prevents unwanted movement in mechanical joints.

---

Maintenance and Inspection

Although it is a passive component, the 3115 1041 00 WASHER ATLAS COPCO should be inspected periodically. Replace the washer if:

• It shows visible cracks or surface flattening.

• Corrosion marks appear on the edges.

• The bolt torque loosens repeatedly.

Under standard conditions, the washer can withstand more than 10 000 tightening cycles.

---

Manufacturing Standards

Each washer supplied by 3GEN Export meets the following quality standards:

• ISO 9001 and ISO 14001 certified production

• Dimensional tolerance of ± 0.02 mm

• Hardness verification per Vickers testing

• Surface roughness ≤ Ra 1.6 µm

This strict quality control ensures consistent performance across every production batch.

---

Load Distribution and Mechanical Role

When bolts tighten against surfaces without a washer, the concentrated force can dent the metal, leading to fatigue cracks. The 3115 1041 00 WASHER ATLAS COPCO prevents this by evenly distributing the applied force, maintaining sealing integrity around hydraulic connections, and preventing micro-leaks.

Its role is small but essential, without it, even high-grade bolts cannot guarantee long-term joint stability.

---

Thermal and Environmental Resistance

The washer operates flawlessly in extreme temperatures from –40 °C to +250 °C. The protective surface coating resists oil, hydraulic fluid, and drilling dust, ensuring dependable use in underground, marine, or quarry environments.

---

Packaging and Delivery

Each 3115 1041 00 WASHER ATLAS COPCO is sealed in moisture-proof packaging and labeled with a QR code for easy traceability.

• Individually bagged and batch-coded.

• Shipped within 24 hours of order confirmation.
