Chain Couplings

Chain couplings are mechanical devices used to connect two rotating shafts, transmitting torque and rotational motion between them. Comprising two sprockets and a roller chain, these couplings accommodate misalignment, absorb shock loads, and reduce vibrations, making them suitable for various industrial applications. Chain couplings are known for their durability, high torque capacity, and ability to operate in harsh environments, with proper lubrication and maintenance essential for optimal performance and longevity.
