In the context of engineering and manufacturing, an industrial chain is a heavy-duty power transmission or material handling component made of a series of connected links. While they look like the chain on a bicycle, industrial versions are engineered to move massive loads, endure high heat, and resist corrosive chemicals.
An industrial sprocket is a profiled wheel with teeth that mesh with a chain, track, or other perforated material. While they look like gears, they are fundamentally different: gears mesh directly with other gears, whereas sprockets never touch each other—they always use a chain to transmit power over a distance.
