This 8-inch by 3-inch 71 series caster has the highest load capacity rating in our line-up of single ball race swivel sections. The bearings in the swivel section act as both load and thrust components and lock the swivel section together to distribute the load over a larger area.
Combined with Forged Steel wheels, these casters become a powerhouse solution for heavy-duty industrial applications. These wheels are hot forged from high carbon steel billets, enhancing their grain structure, ductility, and tensile strength (64,000 psi). With precision machining, they meet tight tolerances, ensuring flat surfaces with rounded edges. Offering the greatest load capacity, impact strength, and rollability among caster wheels. With the proper wheels and bearings, these wheels are capable of withstanding temperatures up to 800 degrees. Packed with our straight roller bearings, which are most effective for heavy loads, and are a great option when facing excessive thrust loading, these casters are rated for 4500 lbs.
