Big Size Shaft Coupling

No products were found matching your selection.
AODISI offers a robust range of big size shaft couplings, engineered to handle high torque, heavy loads, and large shaft diameters in industrial machinery and heavy – duty equipment. These couplings are designed to transmit power efficiently between large rotating shafts while accommodating misalignments, reducing vibration, and protecting connected components from shock loads.

 

Crafted from premium materials tailored to extreme working conditions:

 

  • High – grade alloy steel (42CrMo, 35CrMo) for exceptional tensile strength and torque capacity, ideal for heavy – duty applications in mining machinery, steel mills, and large – scale industrial gearboxes.
  • Nickel – chromium alloy steel for enhanced heat resistance, suitable for high – temperature environments such as power generation equipment (turbines, generators) and metallurgical processing lines.
  • Duplex stainless steel for superior corrosion resistance, perfect for marine propulsion systems, offshore drilling rigs, and chemical processing plants with harsh, corrosive media.

 

AODISI’s standard big size shaft couplings are available in various types to meet specific alignment and load requirements:

 

  • Flanged couplings, offering high rigidity and torque transmission for large – diameter shafts (ranging from 100mm to 800mm) in applications like industrial pumps and compressors.
  • Gear couplings, designed to accommodate angular, parallel, and axial misalignments, making them suitable for heavy – duty conveyors, rolling mills, and crane systems, with working torque capacities up to 500,000N·m.
  • Diaphragm couplings, providing zero backlash and high precision for high – speed, high – torque machinery such as large motors, turbines, and centrifuges, ensuring minimal vibration and maintenance – free operation.

 

Moreover, AODISI can customize big size shaft couplings with special features on request, including:

 

  • High – strength bolts with anti – loosening treatments for reliable long – term operation.
  • Surface treatments like phosphating, painting, or galvanizing to enhance corrosion resistance in outdoor or humid environments.
  • Integrated torque measurement sensors for real – time monitoring in critical power transmission systems.

 

Each big size shaft coupling is clearly marked with the AODISI trademark, maximum torque rating, shaft diameter range, and applicable standards (such as DIN or ISO), allowing for easy identification and selection.

 

All of AODISI’s big size shaft couplings are meticulously manufactured in their advanced Chinese production facilities, adhering to strict quality management systems and precision machining processes. They comply with international standards such as ISO 9001 and ISO 14001, ensuring durability, safety, and performance in the most demanding industrial environments.
