Material handling products are vital components to many industrial and manufacturing operations. Carts, trucks, and dollies safely move and maneuver heavy and large items. Casters come in a wide range of sizes and styles and are typically available with plates mounted to them. Key elements to consider when selecting casters include wheel diameter, load capacity, rolling force, and wheel material. Chains and sprockets, such as flat conveying chains and engineering class chains and sprockets, easily allow rotary motion and are used in motor vehicles, conveyors, and manufacturing machinery.
