SHEAVE ASSEMBLY

grabcad

A sheave, also known as a pulley wheel, is a circular wheel with a grooved hole in its center, used to guide and reduce friction for ropes or cables in various mechanical systems like hoists, cranes, and block-and-tackle. The term 'sheave' originates from the Old English word 'scyf', referring to a cutting tool with a sharp edge. In modern applications, sheaves are made of materials such as brass, bronze, nylon or steel, depending on the specific requirements of the system they are used in.
