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.
Paired with our general-purpose, 1-inch thick tread, H.D. 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. This wheel is capable carrying loads up to 3700 lbs. and has a 1-inch thick tread which is denoted by the H.D. in the wheel material. 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 3100 lbs.
