Product Description
Main products
Coupling refers to a device that connects 2 shafts or shafts and rotating parts, rotates together during the transmission of motion and power, and does not disengage under normal conditions. Sometimes it is also used as a safety device to prevent the connected parts from bearing excessive load, which plays the role of overload protection.
Couplings can be divided into rigid couplings and flexible couplings.
Rigid couplings do not have buffering property and the ability to compensate the relative displacement of 2 axes. It is required that the 2 axes be strictly aligned. However, such couplings are simple in structure, low in manufacturing cost, convenient in assembly and disassembly, and maintenance, which can ensure that the 2 axes are relatively neutral, have large transmission torque, and are widely used. Commonly used are flange coupling, sleeve coupling and jacket coupling.
Flexible coupling can also be divided into flexible coupling without elastic element and flexible coupling with elastic element. The former type only has the ability to compensate the relative displacement of 2 axes, but cannot cushion and reduce vibration. Common types include slider coupling, gear coupling, universal coupling and chain coupling; The latter type contains elastic elements. In addition to the ability to compensate the relative displacement of 2 axes, it also has the functions of buffering and vibration reduction. However, due to the strength of elastic elements, the transmitted torque is generally inferior to that of flexible couplings without elastic elements. Common types include elastic sleeve pin couplings, elastic pin couplings, quincunx couplings, tire type couplings, serpentine spring couplings, spring couplings, etc
Coupling performance
1) Mobility. The movability of the coupling refers to the ability to compensate the relative displacement of 2 rotating components. Factors such as manufacturing and installation errors between connected components, temperature changes during operation and deformation under load all put CHINAMFG requirements for mobility. The movable performance compensates or alleviates the additional load between shafts, bearings, couplings and other components caused by the relative displacement between rotating components.
(2) Buffering. For the occasions where the load is often started or the working load changes, the coupling shall be equipped with elastic elements that play the role of cushioning and vibration reduction to protect the prime mover and the working machine from little or no damage.
(3) Safe, reliable, with sufficient strength and service life.
(4) Simple structure, easy to assemble, disassemble and maintain.
How to select the appropriate coupling type
The following items should be considered when selecting the coupling type.
1. The size and nature of the required transmission torque, the requirements for buffering and damping functions, and whether resonance may occur.
2. The relative displacement of the axes of the 2 shafts is caused by manufacturing and assembly errors, shaft load and thermal expansion deformation, and relative movement between components.
3. Permissible overall dimensions and installation methods, and necessary operating space for assembly, adjustment and maintenance. For large couplings, they should be able to be disassembled without axial movement of the shaft.
In addition, the working environment, service life, lubrication, sealing, economy and other conditions should also be considered, and a suitable coupling type should be selected by referring to the characteristics of various couplings.

Temperature and Pressure Limits of Stainless Steel Couplings
The temperature and pressure limits of stainless steel couplings can vary depending on the specific design, size, and material of the coupling. In general, stainless steel couplings are known for their excellent temperature and pressure resistance, making them suitable for a wide range of applications, including high-temperature and high-pressure environments.
Temperature Limits:
Stainless steel couplings can typically handle a wide temperature range, from as low as -100°C (-148°F) to as high as 800°C (1472°F) or even higher for specialized high-temperature applications. However, the exact temperature limits depend on factors such as the grade of stainless steel used, the presence of any seals or elastomeric components, and the intended application. Some stainless steel couplings are specifically designed for extreme temperatures in industries like aerospace, oil and gas, and chemical processing.
Pressure Limits:
Stainless steel couplings are known for their excellent strength and resistance to pressure. They can handle pressures ranging from a few hundred PSI (pounds per square inch) to several thousand PSI, depending on the coupling’s size and design. High-pressure stainless steel couplings are commonly used in hydraulic systems, oil and gas pipelines, and heavy machinery applications where reliable sealing and pressure containment are critical.
It is important to consult the manufacturer’s specifications and technical data to determine the exact temperature and pressure limits of a specific stainless steel coupling model. Using the coupling within the specified limits ensures optimal performance and avoids potential failure or damage.
Differences Between Stainless Steel Couplings and Aluminum or Carbon Steel Couplings
Stainless steel couplings, aluminum couplings, and carbon steel couplings are commonly used in various industrial applications, but they differ in their material properties, performance characteristics, and suitability for specific environments.
