3128240300 – 3128 2403 00 JAW ATLAS COPCO

The 3128 2403 00 JAW ATLAS COPCO is a precision-engineered structural component designed to ensure reliable gripping, clamping, and alignment inside high-performance ATLAS COPCO hydraulic and pneumatic rock drilling systems. Its geometry, surface treatment, load-carrying capability, and long-cycle durability make it one of the most critical elements in the entire drill rig mechanism. Whether the machine is operating in mining, tunneling, quarrying, or large-scale construction, the jaw plays an essential role in stabilizing components under continuous vibration, shock loads, dust exposure, and extreme working pressures.

This product has been meticulously developed to provide dependable mechanical engagement within the drifter assembly. In ATLAS COPCO systems, the 3128 2403 00 JAW ATLAS COPCO typically works in conjunction with moving pistons, sleeves, guides, and structural housings. It must endure repetitive cycles while maintaining dimensional stability, resisting micro-abrasion, and securing critical alignment tolerances.

3GEN Export supplies the 3128240300 JAW as a high-grade OEM-level spare manufactured to match the material strength, tolerances, and longevity required by ATLAS COPCO drilling engineers. Our strict machining standards and surface finishing methods ensure that each jaw provides excellent functionality with minimal maintenance intervals.

Below, you will find a deeply detailed technical, mechanical, and operational analysis designed for engineers, procurement specialists, machine rebuilders, and drilling experts requiring an in-depth understanding of the part.

Role of the 3128 2403 00 JAW ATLAS COPCO in Drilling Machinery

The 3128 2403 00 JAW ATLAS COPCO serves as a fixed and load-bearing anchoring component inside the drifter’s mechanical architecture. In rock drills, jaws are typically used to:
• Support and secure guide bushing assemblies
• Absorb axial and radial forces during piston strikes
• Maintain alignment of rotating or reciprocating components
• Reduce structural deflection under vibration
• Provide precise seating surfaces for internal mechanisms

In heavy rock-drilling systems, all structural parts are exposed to intense stress conditions. Jaw components must therefore tolerate:
• Thousands of per-minute vibration cycles
• High-impact forces from striker pistons
• Cyclic torque loads
• Fine dust, moisture, and temperature fluctuations
• Constant metal-to-metal micro-contact

If a jaw loses rigidity, alignment is compromised. This creates uneven wear in shank adapters, piston rods, rotation units, and guides. Over time, it may lead to catastrophic damage. The 3128240300 JAW prevents such failures by providing stable geometric equilibrium for the entire assembly.

Material Engineering Characteristics

The 3128 2403 00 JAW ATLAS COPCO is produced from high-strength alloy steel that has undergone a series of critical metallurgical treatments:
• Forging for improved grain structure
• Precision CNC machining for dimensional tolerance
• Heat-treating for increased hardness and fatigue resistance
• Surface finishing to reduce friction and wear
• Micro-polishing to improve contact stability

These processes enhance:
• Structural rigidity
• Impact resistance
• Wear life
• Tensile strength
• Surface hardness in critical load zones

The multi-contour geometry of the jaw provides optimized distribution of compressive forces. Each internal radius, machined edge, and mounting point is intentionally designed to resist shearing and deformation even under extreme mechanical load.

Dimensional Performance and Mounting Stability

The 3128 2403 00 JAW ATLAS COPCO includes several precisely machined mounting holes and contact surfaces. These ensure:
• Easy integration into the drifter structure
• Accurate positioning of the adjoining shaft or guide
• High resistance to displacement under load
• Stable surface-to-surface contact with the machine frame

The mounting holes are aligned for balanced load transmission. Incorrect positioning or counterfeits can create misalignment of key components like pistons, bearings, and sleeves. The 3128240300 JAW guarantees consistent machine geometry.

Mechanical Behavior Under Heavy-Duty Applications

In mining and tunneling, machine heads may operate continuously for long shifts—often in conditions involving:
• Shock impacts
• Abrasive dust
• Water flushing
• Hydraulic surges
• Extreme temperature variations

The 3128240300 – 3128 2403 00 JAW ATLAS COPCO withstands these conditions due to:
• Reinforced architecture
• High load-bearing walls
• Stress-relieved sections that prevent crack propagation
• Optimized mass distribution for vibration control

Its reinforced central curvature acts as a structural shield, balancing internal machine forces and reducing wear on surrounding components.

Compatibility With ATLAS COPCO Models

The 3128 2403 00 JAW ATLAS COPCO is typically used in the following rock drill models:

• ATLAS COPCO COP 1838
• ATLAS COPCO COP 1038
• ATLAS COPCO COP 1132
• ATLAS COPCO COP 1838ME
• ATLAS COPCO COP 1638
• ATLAS COPCO Tunneling and Quarrying Drill Families (varies by configuration)

If you require confirmation for a specific drill type, 3GEN Export provides compatibility verification support for all technical inquiries.
