Super heavy (> 500kg) : preferred choice of steel wheel hub + polyurethane tire
Core advantage
Super load-bearing capacity
Steel wheels: provide rigid support structure, single wheel load can reach 100~500kg or higher, suitable for heavy equipment (such as forklift, machine tools, medical carts).
Polyurethane tire: disperses pressure and enhances overall stability to avoid deformation due to excessive weight.
Wear resistance and durability
Polyurethane tire: high hardness (Shore 80~100°), excellent wear resistance, far longer than ordinary rubber or TPR casters.
Steel wheels: strong impact resistance, not easy to break, especially suitable for frequent movement or rugged road scenes.
Key selection suggestions：
Chemical resistance
Polyurethane tire: acid and alkali resistance, oil resistance is good (part of the formula can resist weak acid and weak alkali), suitable for chemical workshops, food processing plants and other scenes.
Steel wheels: The surface can be galvanized or sprayed with anti-rust coating to enhance corrosion resistance.
Easy to clean and hygienic
Polyurethane tire: smooth surface, not easy to accumulate ash, can be quickly wiped and sterilized, in line with the clean room requirements of medical and pharmaceutical industries.
Steel wheel: no pore structure, avoid dirt, reduce the risk of bacterial growth
