A cylindrical hinge, also known as a barrel hinge or pivot hinge, is a type of hinge that allows two parts to rotate around a central axis, typically in a cylindrical or barrel-shaped housing. These hinges are often used in applications where a clean, compact design is needed, as the hinge mechanism is largely concealed within the cylindrical structure.
