Jaw couplings are functional as the industrial power transmission devices for all-purpose. They can be used in a vast range of temperatures and are made to manage the angular misalignment. Plus, they can manage the accompanying reactionary loads. These withstand chemicals and boast of good speed and dampening abilities. Jaw couplings feature hubs and elastomeric inserts. The couplings can work for a long time and are suited for several applications. These are serviceable as the three-piece flexible shaft connectors which can connect driving as well as driven beams in mechanical power transmission constructions. Usually, they are used for large industrial machines such as blowers, compressors, pumps, mixers, etc.
