Couplings
Couplings are mechanical devices that connect rotating shafts to transmit torque. They come in various types, including rigid, flexible, gear, magnetic, fluid, and universal couplings, as well as special types such as chain, bellows, quick-locking, and shock-absorbing couplings, each suited to specific needs. They find applications in industries ranging from automotive to heavy machinery, ensuring smooth power transfer and reducing vibrations.
