Nylon Caster Wheels
These wheels weigh very little yet they have a load capacity comparable to most metal wheels. They will not develop a flat spot. Nylon wheels are a better choice in wet and corrosive applications which require both chemical resistance and a higher load capacity.
Not recommended if the acid content exceeds 10% of your solution.
