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

This 4-piece Heavy Duty Caster Set with black plastic wheels delivers strength, durability, and easy mobility for demanding applications. Offered in multiple set configurations—rigid, swivel, swivel with brake, or mixed combinations—these casters adapt to a wide range of equipment needs. Wheel sizes from 4" to 8" feature a 2" tread width and load capacities ranging from 600 lbs to 900 lbs per caster. The injection-molded polyolefin or polypropylene wheels are lightweight, impact-resistant, and non-marking, providing excellent floor protection while resisting chemicals, oils, solvents, and water. Cold-forged top plates, hardened raceways, and a double row ball bearing swivel raceway enhance strength and ensure smooth performance. All metal components are zinc-plated for corrosion resistance, while Zerk fittings allow easy lubrication and extended service life. Perfect for platform trucks, food service equipment, and large stock carts, these casters combine a lightweight design with heavy-duty capabilities.
