Heavy Duty Caster Set 6in Polyurethane on Plastic Wheels, 2 Rigid & 2 Swivel with Brake, 4PK

This 4-piece Heavy Duty Caster Set with polyurethane on plastic wheels offers excellent load capacity, smooth rolling, and long-lasting durability for demanding applications. Available in various configurations-rigid, swivel, swivel with brake, or mixed sets-these casters can be customized to meet specific mobility requirements. Wheel sizes range from 4in to 8in in diameter, each with a 2in tread width and roller or Delrin bearings for effortless load handling. The polyurethane tread on a plastic core provides superior wear resistance, floor protection, and shock absorption while outlasting traditional rubber wheels. Cold-forged top plates, hardened raceways, and double row ball bearing swivel construction deliver maximum strength under heavy use. Zinc-plated components resist corrosion, and Zerk fittings in the swivel race make lubrication quick and easy. Ideal for platform trucks, food service equipment, and large stock carts, these casters combine strength and maneuverability for heavy-duty performance.
