Jaw couplings are mechanical devices used to connect two shafts, allowing them to transmit torque while accommodating slight misalignments. They consist of two hubs with interlocking jaws and an elastomeric element, which provides flexibility and shock absorption. This design helps reduce wear and tear on connected machinery. These couplings are commonly found in various applications, including electric motors, pumps, and conveyors. Their simple design and ease of installation make them a popular choice in industries where reliable power transmission is essential. Additionally, jaw couplings are available in different sizes and materials to suit specific operational needs.
