Coupling serve as key connection and control parts for mechanical transmission systems, which is a device that is used to connect two shafts together for power transmission.During power transmission, couplings can absorb shock, vibration and heat due to which they are important in many mechanical applications.
In manufacturing facilities, couplings connect motors to pumps, compressors, conveyor devices and other mechanical equipment. They ensure steady power transmission, shield premium devices from vibration harm and shaft misalignment. They also deliver reliable performance for production processes demanding high operational stability.
