Jaw couplings are one of the first and still most widely used elastomer couplings in the world due to their inherent simplicity. Two identical hubs with three face lugs are connected through a star shaped element, sometimes referred to as an insert or spider. The three-piece design makes them simple to work with and popular on applications such as pumps, fans, blowers and compressors. Jaw couplings require no lubrication and provide high-reliability for light to medium-duty applications with good alignment of equipment and no requirement for torsional dampening. In normal operating conditions there is no metal to metal contact so the life of the hubs is virtually indefinite. However, in a catastrophic failure of the element the load would still be carried by the hubs providing a degree of failure protection. Jaw couplings are resistant to oil, dirt, moisture and grease.
