Where this product is used EasyRoll conveyor rollers and components are the building blocks of gravity flow lines in distribution, manufacturing, and logistics. Gravity conveyor lines for picking, packing, and distribution operations Manufacturing assembly lines using roller conveyors for component flow Postal, retail, and logistics operations with manual flow conveyors Selecting the right option Roller spacing is matched to the smallest item being conveyed — the load should always be supported by at least three rollers. Roller diameter and wall thickness affect load capacity; polypropylene suits light to medium loads, steel rollers suit heavier products. Line length and gradient determine whether gravity flow is achievable without power.
