4 Heavy Duty Caster Set 4" Red Polyurethane on Cast Iron Wheels - 2 Rigid + 2 Swivel with Brake

This 4-piece Heavy Duty Caster Set with red polyurethane on cast iron wheels delivers outstanding strength, durability, and smooth mobility for demanding applications. Available in multiple set configurations—rigid, swivel, swivel with brake, or mixed combinations—these casters are designed to handle a wide range of load requirements. Wheel diameters from 4" to 8" with a 2" tread width offer load capacities from 700 lbs to 1,100 lbs per caster, making them ideal for heavy-duty equipment. The polyurethane tread on a cast iron core provides exceptional durability, floor protection, and resistance to most chemicals, oils, grease, and water. Cold-forged top plates, hardened raceways, and a double row ball bearing swivel raceway ensure reliable performance under heavy loads. Zinc-plated metal parts enhance corrosion resistance, while Zerk fittings allow easy lubrication for long-term maintenance. Perfect for platform trucks, food service equipment, and large stock carts, these casters combine strength, stability, and long-lasting performance.
