The Twin Spring Coupling TSC8300 allows the coupling to be scaled up or down to suit the application and torque requirements. The flexible springs allow for a greater degree of movement without damaging the driveshaft or components, and also absorbs shock and energy, making the coupling more efficient. With this coupling, there are no internal components, eliminating the need for constant maintenance. The TSC8300 is warrantied to 300 ft-lbs of torque.
