Mingwei’s engineering team addresses the most frequent questions regarding the selection, operation, and maintenance of industrial casters. Get precise solutions to your pain points below.

For a single piece of equipment, which wheel material should I choose — PU, rubber, or nylon? It depends on the application.

PU (Polyurethane) Wheels Choose PU wheels for heavy loads with smooth, quiet rolling and excellent resistance to wear, oil, and chemical corrosion. They are the go-to option for clean workshops, warehouses, and automated handling lines where floor protection and durability matter most.

Rubber Wheels Choose rubber wheels for high-elasticity shock absorption on uneven floors or long transport distances. Their soft tread grips the ground well, reduces vibration, and protects sensitive loads, but they are generally better suited to lighter and medium-duty conditions.

Nylon Wheels Choose nylon wheels when the priority is rigidity and high-temperature or chemical resistance. Nylon rolls with low resistance, carries high static load capacities, and works well in environments with frequent temperature changes — ideal for fixed-station or short-distance positioning.

Quick Selection Guide

• Heavy load + smooth floors → PU
• Rough floors + vibration reduction → Rubber
• High temperature / chemicals / static positioning → Nylon
