What are Flexible Couplings?

Couplings join together two shafts as a way of transmitting power from one to the other. It is part of the drivetrain which may include other power transmission components such as lead screws or ball screws, gearboxes, belts and pulleys or chains. There are two fundamental types of couplings; rigid and flexible. Rigid couplings are generally used in... [Read more]

Bellows Couplings

One form of flexible coupling with very low and near zero-backlash is the bellows coupling.
