Heavy Duty Caster Set 4in Rubber on Cast Iron Wheels, 4 Rigid, 4PK

This 4-piece Heavy Duty Caster Set with rubber on cast iron wheels combines strength, durability, and smooth mobility for a wide range of industrial applications. Available in multiple configurations-rigid, swivel, swivel with brake, or mixed sets-it allows for customized maneuverability to match your needs. Wheel diameters range from 4in to 8in, each with a 2in tread width and roller bearings for smooth load handling. The cushion rubber tread on a cast iron hub provides excellent floor protection, reduces noise, and absorbs shock for a smoother ride. Cold-forged top plates, hardened raceways, and double row ball bearing swivel construction ensure long-lasting strength and stability. Zinc-plated components protect against corrosion, while Zerk fittings in both the swivel race and hub make lubrication easy. Ideal for heavy duty platform trucks, food service equipment, and large stock carts, these casters deliver dependable performance under demanding conditions.
