Here are some key differences between chair casters and heavy-duty:
1. Load Capacity:
Chair casters: can support only the weight of the person
Heavy-duty: can support the weight of machinery and other equipment
2. Materials :
Chair casters made of lighter materials like nylon, rubber, or polyurethane, and so on.
Heavy-duty caster made of cast iron or steel, so it cannot carry a lot of loads
3. Floor Protection:
Chair casters are designed to be floor-friendly, with no any mark on the floor
Heavy-duty casters sometimes can make a mark on the floor
