4 Inch Heavy Duty Cast Iron Core PU Caster Wheels – Industrial Mobility Solution

These 4 inch heavy duty caster wheels feature a cast iron core combined with a high-performance polyurethane (PU) tread, delivering excellent load capacity, durable wear resistance, and smooth rolling performance. The cast iron core provides superior structural strength and impact resistance for industrial equipment and carts, while the PU tread reduces noise, protects floors, and ensures easy maneuverability. Precision double ball bearings allow steady 360° swivel action for flexible direction changes.

Designed for heavy duty material handling and industrial mobility, these cast iron core cast PU caster wheels are ideal for moving machinery, warehouse carts, assembly trolleys, work platforms, and other mobile equipment. The 360° swivel capability enables smooth and flexible movement even in tight spaces, while optional brake versions enable secure stopping and locking for safety during loading or stationary operations.

These heavy-duty cast iron core PU caster wheels are well-suited for factory floors, workshops, logistics centers, heavy equipment carts, assembly lines, machine bases, platform trucks, and other industrial or commercial applications where load strength and mobility are critical. They are especially useful in environments that require frequent repositioning of heavy loads while protecting the floor surface.
