Heavy Duty Caster Set 8in Red Polyurethane on Cast Iron Wheels, 2 Rigid & 2 Swivel, 4PK

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 4in to 8in with a 2in 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.
