Restore your heavy-duty equipment with the perfect balance of massive load capacity and floor protection. Our Polyurethane on Iron Replacement Wheels are engineered for high-demand industrial environments where you need the indestructible strength of a metal core combined with a quiet, shock-absorbing ride. These wheels are the industry standard for automotive assembly, warehouse tugger carts, and heavy-duty machinery dollies. Industrial Resilience & Floor Safety: Heavy-Duty Cast Iron Core: Provides a rigid, indestructible foundation that will not warp, bend, or fail under extreme static loads. Non-Marking Polyurethane Tread: Our high-grade poly is chemically and mechanically bonded to the iron core to prevent "chunking" or tread separation. It protects expensive epoxy and finished concrete floors while reducing ambient noise. Smooth-Glide Roller Bearings: Each replacement wheel comes standard with a heavy-duty roller bearing and a 1/2" ID spanner bushing, ensuring low rolling resistance and effortless maneuverability. Chemical & Oil Resistant: Designed to withstand exposure to grease, oils, and common industrial chemicals without degrading the tread. Technical Specifications for Easy Replacement: Load Rating: Massive 1,250 lbs per wheel capacity. Universal Fit: Industry-standard 2-inch tread width fits almost all heavy-duty industrial caster frames. Sizes Available: 4", 5", 6", and 8" diameters to match your existing setup. Temperature Range: Reliable performance in environments from -40°F to +180°F. Repair Your Fleet for Less. Don't replace the whole caster when you can simply upgrade the wheel.
