What is the difference between rigid and flexible coupling?


There are two types of couplings: rigid and flexible. Rigid couplings are used to connect two shafts that are aligned with each other. Flexible couplings are used to connect two shafts that are not aligned with each other.

Flexible couplings are good for when the shafts are a little bit off, while rigid couplings can’t tolerate any misalignment.
