Couplings are devices used to connect two shafts together and are divided into two categories: Rigid and Flexible.

Both are used for the purpose of transmitting power, rigid couplings being more limited in applications as compared to flexible couplings. Rigid couplings are used where shafts are already positioned in precise lateral and angular alignment. Their design does not allow for any misalignment between shafts, but are generally able to transmit more power than flexible couplings. Flexible couplings are designed to accommodate misalignment between shafts and various types of load conditions.

Tighten the set screws to fasten these couplings to your shaft. Set screws bite into the shaft to hold the couplings in place. All are lightweight, corrosion-resistant aluminum.
