Structural Design and Material Integrity
High-Grade Aluminum Alloy Construction
The 3128314013 Holder Set Atlas Copco is constructed from high-strength aluminum alloy, offering the perfect balance of low weight and high rigidity. This advanced material composition ensures exceptional dimensional stability, even when subjected to high vibration and repetitive mechanical loads.
Its CNC-machined body provides precise tolerances, guaranteeing an exact fit within the assembly framework of Atlas Copco drilling rigs. The anodized surface layer further protects against corrosion, moisture, and environmental wear, ensuring long-lasting performance even in humid or saline work environments.
Polyurethane Wear-Resistant Edge
The holder set includes a yellow polyurethane edge insert, which acts as a shock-absorbing and friction-reducing component. This polymer layer ensures smooth contact between metal parts and minimizes the risk of surface wear, while also serving as a protective buffer during rapid tool changes or impact events.
Optimized Mounting Geometry
The elongated mounting slots visible on the 3128 3140 13 Holder Set Atlas Copco allow flexible positioning during installation, simplifying alignment within various machine configurations. This adaptive design not only improves assembly efficiency but also provides better distribution of mechanical stress, resulting in improved fatigue resistance and enhanced system longevity.
Performance Characteristics
Vibration Absorption and Structural Balance
In rock drilling and excavation machinery, constant vibration is one of the leading causes of component wear and misalignment. The 3128314013 Holder Set Atlas Copco effectively mitigates this challenge through its combination of rigid aluminum and flexible polyurethane. The result is a stable support mechanism that maintains precise alignment even under prolonged operation.
High Resistance to Environmental Stress
The anodized coating of this holder set resists oxidation, dust corrosion, and fluid exposure. Even in harsh outdoor or underground environments, the component’s surface finish remains intact, extending maintenance intervals and reducing replacement frequency.
Load Distribution Efficiency
The dual-slot mounting design and internal bracing system enable even load transfer throughout the holder’s body. This engineering detail prevents concentrated stress points, thus protecting adjacent machine parts like liners, guides, and brackets from deformation.
