after trying this product I can confidently say that it`s one of the best casters for industrial and scientific use in the market. The sturdy construction is remarkable and can hold an immense amount of weight with ease. This caster is easy to maneuver and has smooth turning ABILITIES .The only downside i experienced is that it can be a bit noisy during transportation, but that's a small price to pay for such a high-quality product. Overall, I would highly recommend these casters to anyone looking for reliable and durable material handling products..
