Material handling equipment such as platform carts, platform trolleys and platform trucks depends on reliable PU on Cast Iron Casters to ensure smooth movement, stable operation and long service life. Selecting the wrong caster wheels often results in difficult handling, excessive rolling resistance, premature wheel wear and increased maintenance costs. Designed for demanding industrial environments, CMCL PU on Cast Iron Casters provide an ideal solution for manufacturers and users of heavy duty platform transport equipment.

| 5" | 125x50 | 165 | 113x100 | 84x71 | 350 |
| 6" | 150x50 | 192 | 113x100 | 84x71 | 400 |
| 8" | 200x50 | 242 | 113x100 | 84x71 | 450 |
Every Heavy duty PU on Cast Iron Casters combines a high-strength cast iron wheel core with a premium polyurethane tread. This construction delivers excellent load-bearing performance while reducing floor noise and resisting wear, making these industrial casters suitable for continuous operation on concrete, epoxy and other hard factory floors.
Choosing the correct PU on Cast Iron Caster depends on the weight of the equipment, floor conditions and transport frequency.
The 4 inch and 5 inch PU on Cast Iron Casters are widely used on medium-duty platform carts, warehouse trolleys and workshop transport equipment. They offer excellent maneuverability while supporting substantial loads.
For heavier industrial applications, the 6-inch PU on Cast Iron Casters provide improved obstacle-crossing ability and lower rolling resistance, making them one of the most popular choices for heavy-duty platform trucks.
When transporting oversized machinery or palletized goods, 8 inch PU on Cast Iron Casters with a maximum capacity of 450 kg per wheel deliver smoother movement, improved stability and reduced pushing effort over long distances.
Compared with standard rubber wheels or plastic wheels, PU on Cast Iron Casters offer several significant advantages:
High load capacity supported by a robust cast iron wheel core Excellent wear resistance for long-term industrial operation Lower rolling resistance for easier manual handling Quiet movement with reduced floor vibration Non-marking polyurethane tread that helps protect epoxy and concrete floors Suitable for warehouses, factories, logistics centers and manufacturing plants.
These advantages make PU on Cast Iron Casters one of the preferred solutions for industrial material handling equipment.
CMCL PU on Cast Iron Casters are available in swivel, rigid and brake configurations.
Swivel casters provide excellent maneuverability in confined workspaces, rigid casters improve straight-line travel for heavy loads, and brake casters securely lock both the wheel and swivel mechanism to prevent unwanted movement during loading or unloading.
Many OEM manufacturers and equipment builders choose CMCL PU on Cast Iron Casters as standard components for platform carts, platform trolleys and industrial transport equipment.
Besides offering excellent durability, every size shares the same mounting plate dimensions, simplifying inventory management and reducing replacement costs. The flat polyurethane tread ensures stable ground contact, while the cast iron wheel core maintains structural integrity under continuous heavy-duty operation.
Whether you require replacement wheels for existing equipment or OEM caster solutions for new platform trucks, CMCL PU on Cast Iron Casters can be customized to match different load capacities, floor conditions and operating environments.
