What component is used to connect two pieces of shafting together?

The component used to connect two pieces of shafting together is a coupling. Couplings are critical in mechanical systems as they allow for the transmission of torque and rotational power between two shaft ends while accommodating some degree of misalignment, vibration, or axial movement. They can be designed to handle different types of loading and environments, including flexible and rigid options.

Bearings are designed to support and reduce friction between moving parts but do not connect two separate shafts. A gearbox, on the other hand, is a power transmission device that alters the speed and torque of a machine, not primarily meant for connecting shafts. A flange serves as a mechanical component allowing for the connection of two pipes or other equipment, but it is not specifically designed to connect two shafting components directly like a coupling does.
