Similar to elastomeric donut flexible couplings, tire flexible shaft couplings have two hubs and a flexible center section that fits between the hubs to allow the coupling to accommodate moderate amounts of parallel misalignment (shafts are misaligned but parallel), angular misalignment (shafts are set at an angle to each other), and axial misalignment (shafts are pulled apart or pushed together) when the coupling is connected between two shafts.
Shaped like a tire, the center section can be replaced when worn or damaged, and it has a split that allows the tire to be replaced without removing the coupling from the shafts. Made from rubber-like materials, the center section helps dampen vibrations. Tire couplings don't require lubrication and are recommended for low-speed applications.
Set-Screw Mount Hubs
Choose two hubs and connect them with a compatible tire insert to form a tire flexible shaft coupling. These hubs are held in place with the included set screws, which are tightened until they bite into the shaft material. For best results when installing these couplings, select a coupling that has set screws made from a material that is harder than the shaft material.
