Description

3128048100, 3128 0481 00 SHAFT ATLAS COPCO The 3128 0481 00 SHAFT ATLAS COPCO is a precisely engineered transmission component designed to withstand the extreme mechanical forces of hydraulic rock drilling systems. Within Atlas Copco’s drilling assemblies, the shaft plays a central structural and dynamic role: it transfers torque, regulates movement, supports load distribution and safeguards the accuracy of internal kinematic sequences. Built from high-strength alloy steel, machined to microscopic tolerances and hardened for maximum durability, this shaft is designed for the intense cyclic loads that define modern mining, tunneling and construction environments. The 3128 0481 00 SHAFT ATLAS COPCO is also a critical stability element inside the percussion housing. When a rock drill operates, thousands of high-frequency energy cycles pass through the transmission train every minute. A component that is even slightly misaligned, weak or dimensionally inconsistent can compromise the entire mechanism. This is why this shaft is produced using controlled turning, centerless grinding, induction hardening and multi-stage quality inspection. Every surface, every diameter, and every channel is designed for precision, minimal vibration and long service life. 3GEN Export supplies this part as a high-quality OEM-grade replacement with global dispatch within just 5 working days , ensuring operations can resume with minimal downtime. Overview of the 3128 0481 00 SHAFT ATLAS COPCO At the heart of Atlas Copco’s rock drills lies a series of interconnected shafts that coordinate the movement of pistons, bushings, sleeves, couplings and rotation systems. The 3128 0481 00 SHAFT ATLAS COPCO is one of these central mechanical links. Its purpose can differ slightly based on drill configuration, but in all cases it supports three essential functions: Transfer of rotational force Absorption and redistribution of axial loads Maintenance of internal component alignment Where many machine parts act in isolation, a shaft interacts continuously with sleeves, couplings, bearings, glands and rotation blocks. This dynamic relationship is why precision is essential. Any dimensional drift, whether through wear, fatigue or thermal expansion, impacts the entire assembly. The 3128 0481 00 SHAFT ATLAS COPCO is manufactured to solve this exact challenge. Its walls are hardened, its surface is polished, and its internal threads, oil channels and grooves follow a geometry that minimizes friction while preserving lubrication flow. These characteristics collectively enable higher efficiency, cooler operation and longer component lifetimes for the surrounding system. Key Features of the 3128 0481 00 SHAFT ATLAS COPCO High-Strength Alloy Steel This shaft is produced from heat-treated alloy steel, a material chosen for its outstanding tensile strength, resistance to torsional shear and ability to endure massive cyclic stress. Mining and drilling machinery subjects its shafts to repeated loading cycles that exceed hundreds of thousands of impacts per shift. The material used in the 3128 0481 00 SHAFT ATLAS COPCO withstands this without micro-fracture initiation. Advanced Surface Hardening A multi-stage induction hardening process increases surface density, improving wear resistance while maintaining tough cores to prevent brittle failure. This allows: Extended operational lifetime Greater resistance to internal scoring Reduced need for maintenance Lower long-term operating cost Each shaft is designed to survive abrasive dust, vibration, extreme heat and hammer-generated shockwaves. Precision-Machined Dimensions Accuracy is essential in Atlas Copco rock drills. Even a small deviation in roundness, concentricity or diameter tolerance can cause: Excessive vibration Misalignment of internal components Poor lubrication distribution Shortened lifespan of bearings and bushings The 3128 0481 00 SHAFT ATLAS COPCO avoids these failures by following tight machining tolerances applied through CNC turning and grinding. Optimized Lubrication Flow The shaft features lubrication openings, internal bores or grooves (depending on the drill architecture) to ensure consistent lubrication distribution throughout the rotating system. Proper lubrication reduces: Heat buildup Metal-to-metal contact Surface scoring Seizure risks In high-duty drilling, consistent lubrication flow is absolutely essential for performance and longevity. Corrosion-Resistant Treatment The shaft undergoes anti-corrosion finishing to protect against: Rock dust contamination Humidity Water ingress Chemical exposure This ensures stable long-term performance even in underground humidity or wet drilling environments. Functionality of the 3128 0481 00 SHAFT ATLAS COPCO Because this shaft is positioned within the mechanical center of the drill’s rotation or percussion sub-assembly, it provides the following critical operational functions: 1. Torque Transmission This is one of the shaft’s primary functions. Rotational torque is transferred from the drill’s rotation motor to the drill string. The shaft must: Withstand high torsional stress Maintain dimensional accuracy Prevent twisting or warping When the shaft fails, drilling efficiency drops instantly, causing the entire hammer to stall. 2. Structural Support Inside the drill housing, the shaft helps maintain structural alignment by keeping bushings, bearings and sleeves in their precise operational paths. Proper alignment prevents the drill from: Vibrating excessively Wearing down bushings prematurely Misfiring or overheating The 3128 0481 00 SHAFT ATLAS COPCO is engineered to act as a stabilizing backbone for the surrounding mechanical components. 3. Axial Load Management Percussion drilling subjects the assembly to heavy backward and forward impacts. The shaft must: Carry axial loads without bending Distribute load evenly across assemblies Protect weaker surrounding parts Without a durable shaft, overload forces could damage multiple parts simultaneously. 4. Lubrication Control Through internal channels, openings or alignment grooves, the shaft works as a controlled passage for lubrication. Maintaining internal lubrication is essential for: Cooling Minimizing friction Reducing metail-to-metal scoring Maximizing drill efficiency Proper lubrication significantly extends the lifespan of every associated part. Engineering Advantages of the 3128 0481 00 SHAFT ATLAS COPCO High Vibration Resistance Drilling machinery generates tremendous vibrations. Low-grade shafts lose concentricity or develop microcracks under such stress. This shaft resists: Fatigue fracture Vibrational distortion Misalignment It preserves drill alignment even under intense shock cycles. Uniform Heat Dissipation The shaft's material and surface finishing ensures controlled thermal behavior. When percussion heats the assembly, the shaft maintains structural stability, preventing thermal expansion issues. Enhanced Compatibility with Support Components Even though specific drill models are not listed here, the shaft is engineered to fit Atlas Copco’s precision-aligned housings, matching: Sleeve interfaces Bearing surfaces Coupling geometries Internal clearances This guarantees smooth integration with the rest of the drill system.
