Jaw couplings provide a cost-effective solution for standard power applications, cushioning moderate shock loads and dampening low vibration levels. Vitually maintenance-free and easy to install, jaw couplings are available with a snap wrap element, allowing element replacement in situ. This makes it the most popular coupling in the world. A complete jaw coupling with spacer consists of 2 hubs, 2 nitrile wrap insert, 2 ring kits and 1 spacer.
