Product Description
FCL Coupling/Shaft Coupling /Pin & Bush Coupling /FCL Flexible Coupling/NBK FCL Coupling is widely used for its compacts designing, easy installation, convenient maintenance, small and light weight.
As long as the relative displacement between shafts is kept within the specified tolerance, couplings will operate the best function and have a longer working life.
Thus it is greatly demanded in medium and minor power transmission systems driven by motors, such as speed reducers, hoists, compressors, conveyors, spinning and weaving machines and ball mills.

How Does a Pin Coupling Protect Connected Equipment from Shock Loads and Vibrations?Pin couplings are designed to provide excellent protection to connected equipment from shock loads and vibrations, ensuring the smooth and reliable operation of the machinery. The unique features of pin couplings contribute to their ability to absorb and dampen shock loads and vibrations effectively:
Overall, pin couplings are reliable and versatile components that can effectively protect connected equipment from shock loads and vibrations. Their flexibility, torsional compliance, damping characteristics, and robust construction make them suitable for various industrial applications where shock and vibration mitigation are essential for maintaining the health and longevity of machinery and equipment. What Industries Commonly Use Pin Couplings for Power Transmission?Pin couplings are widely used in various industries for power transmission due to their ability to accommodate misalignment and provide reliable torque transmission. Some of the industries where pin couplings are commonly employed include:
These are just some examples of the industries where pin couplings are commonly used. Pin couplings offer versatility, ease of installation, and reliability, making them suitable for a wide range of applications in different sectors where power transmission is essential. Understanding Pin Couplings and Their FunctionalityA pin coupling, also known as a shear pin coupling, is a type of mechanical coupling used to connect two rotating shafts in a mechanical system. It is designed to transmit torque while allowing for a limited amount of angular misalignment between the shafts. The primary function of a pin coupling is to protect the connected equipment from torque overload and prevent damage to the shafts and other components in case of sudden shock or overload. How a Pin Coupling Works: A typical pin coupling consists of two hubs, one on each shaft to be connected, and a series of pins that pass through the hubs to join them together. The pins are usually made of a softer material than the hubs, such as brass or aluminum, to act as sacrificial elements. The number and size of the pins depend on the coupling’s torque rating and the required angular misalignment capacity. When the shafts are misaligned, the pins experience shear stress as they bend under the applied load. In normal operating conditions, the pins remain intact and allow the torque to transfer from one shaft to another. However, in the event of an overload or excessive misalignment, the pins will shear off, preventing the transmission of excessive torque and protecting the connected equipment from damage. After shearing, the damaged pins can be easily replaced, and the coupling can be put back into service without major repairs to the equipment. This feature makes pin couplings particularly suitable for applications with varying operating conditions and environments where shock loads or sudden overloads may occur. Advantages of Pin Couplings: – Protection against Overload: The shear pins act as a safety feature, protecting the connected equipment from excessive torque and sudden shocks. – Misalignment Tolerance: Pin couplings can accommodate a limited amount of angular misalignment between the shafts. – Easy Replacement: After shearing, the damaged pins can be quickly replaced, reducing downtime and maintenance costs. – Versatility: Suitable for a wide range of applications, including pumps, compressors, and other industrial machinery. – Cost-Effective: The sacrificial pins are cost-effective components that can be easily replaced, avoiding costly repairs to the main equipment. Limitations: – Pin couplings have lower torque capacities compared to some other coupling types, such as gear couplings or rigid couplings. – The need to replace the shear pins after each failure may lead to frequent maintenance requirements in applications with frequent overloads or misalignments. In summary, pin couplings offer a reliable and cost-effective solution for torque transmission and protection against overloads in various mechanical systems. Their ability to accommodate misalignment and absorb shock loads makes them suitable for a wide range of industrial applications.
