Conveyor Idler / Roller Components

An idler, or roller, is a crucial component in a conveyor belt system that supports the belt and the material being transported. Positioned at intervals along the conveyor's frame, idlers help maintain belt stability, reduce sag, and prevent misalignment, all of which extend the belt's service life.

Gravity Roller Components are integral parts of conveyor systems in various industrial settings, including warehouses, distribution centres, and manufacturing plants, to move, streamlining, sorting and packing operations, transporting goods on assembly lines, loading and unloading trucks at loading docks.
These components typically include bearing housings with bearings to support conveyor rollers, along with seals for shaft protection. They facilitate the smooth movement of goods or materials along the conveyor line, relying of gravity repulsion. Gravity roller components are designed for durability, efficiency and ensuring reliable operation in material handling applications.
