The JS Type Serpentine Spring Coupling is a high-performance flexible shaft coupling designed to transmit torque smoothly while absorbing shock and damping vibrations. It uses a specially formed serpentine (snake-like) spring that interlocks with precision-machined teeth on the inner surfaces of two coupling hubs. This design allows for excellent torque transmission characteristics while providing flexibility to accommodate misalignment and torsional fluctuations.
This type of coupling is well-suited for medium and high-torque applications requiring reliable performance under frequent start-stop, reversing, or variable-load conditions. Its ability to cushion impact loads and reduce vibration makes it ideal for heavy-duty industrial machinery.
Key Features:
High torque capacity with compact design
The serpentine spring ensures strong, stable transmission of torque even under heavy loads.Excellent shock absorption and vibration damping
The spring structure helps protect connected machinery from sudden impact, overload, and torsional vibrations.Good misalignment tolerance
Accommodates angular, axial, and minor radial misalignment, ensuring system flexibility and reliability.Easy maintenance and replacement
The coupling’s modular design allows for easy disassembly and spring replacement without disturbing the connected equipment.Durable construction
Made from high-strength alloy steel with heat-treated springs for extended service life and superior fatigue resistance.
Typical Applications:
The JS Serpentine Spring Coupling is commonly used in:
Gearboxes and reducers
Lifting and hoisting machinery
Conveyors and crushers
Pumps and compressors
Fans and blowers
Heavy-duty industrial equipment with variable or impact loads
Operating Conditions:
Operating temperature: –30°C to +80°C
Suitable for bi-directional rotation
Grease-free dry operation (depending on model)
Available in multiple sizes and torque ratings
Designed for horizontal installations (vertical available upon request)
The JS Type Serpentine Spring Coupling is a robust and reliable solution for applications where smooth torque transfer, misalignment compensation, and shock resistance are essential. Its compact design, high strength, and excellent damping characteristics make it a preferred choice in a wide range of heavy-duty mechanical drive systems.
