This 4-inch by 3.25-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.
Paired with our general-purpose, Standard Polyurethane (Shore 95A Hardness) wheel, this caster becomes good for numerous industrial applications. It is non-marking with high tear strength and resistance to flat spotting, as well as a good solvent and water resistance. 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 1200 lbs.
