Drum Roller Chain is a form of roller chain that is designed for applications in which the chain wraps around a cylindrical or drum-like sprocket. This type of chain is utilised when the sprocket shape differs from the normal flat sprockets used with standard roller chains. The drum roller chain is distinguished by its ability to engage with a curved or cylindrical sprocket smoothly and efficiently. It is extensively utilised in applications where the chain must go around bends or curves, such as conveyor systems. The drum roller chain's flexibility provides for the effective transportation of products or materials over curved or serpentine courses.
