Tire couplings are flexible shaft couplings that transmit torque and rotational motion between two shafts while accommodating misalignment and reducing vibration. They consist of two flanges or hubs and an elastomeric tire element, providing a reliable and low-maintenance solution for connecting shafts in various industrial applications, such as pumps, motors, and gearboxes. Selection depends on factors like torque requirements, shaft diameters, operating speed, and environmental conditions.
