Galvanized gravity rollers are used as the basis for roller conveyor systems for motorless product transport (using tilt/manual push). This type is suitable for receiving, processing, and shipping operations, as well as sorting and order fulfillment lines within warehouses and factories. Typically, it consists of a galvanized roller tube, shaft, and bearing housing to ensure smooth rotation and minimize friction. Various end caps/bearing housings are available depending on the tube and shaft size and chassis design. Heavy-duty versions are widely available for loading stations and industrial handling lines, with hexagonal or other shaft options as required.
