The Heavy Duty 4 Pieces 10 Kg Load Capacity Ball Transfer Caster Wheel is a set of four durable ball transfer units engineered for smooth, multidirectional load movement in light to moderate industrial or commercial applications. Each unit supports up to 10 kg (about 22 lbs), making the set suitable for handling smaller components, tools, or packages with minimal effort. These casters facilitate 360-degree rotation and low-friction sliding, ideal for conveyor systems, workstations, and assembly setups where precise positioning is required without heavy lifting.
