Jaw Couplers Explained: How They Work and Where They're Used
Anyone who works with rotating equipment has probably run into Jaw couplers at some point, whether they realized it or not. These components sit quietly at the connection point between two shafts, doing the unglamorous but essential work of transferring torque while absorbing shock and compensating for minor misalignment. When a motor needs to drive a pump, fan, or conveyor, something has to bridge that gap reliably, and that's exactly the job jaw couplers are built for. Despite how common they are in industrial settings, a lot of confusion still surrounds jaw couplers, particularly around how they're constructed, what makes them different from other coupling types, and how to pick the right one for a given application. This article breaks down the basics so you can make more informed decisions the next time you're specifying or replacing a coupling on your equipment. What Are Jaw Cou...
