The below capacity ranges indicate the working (dynamic) load that each caster will support. A safety factor should be included in your formula to determine your required load rating per caster.

W/(C-1)=R W is total weight needed to move. C is total number of casters required. R is ideal load rating, with safety factor built in. Divide the total load weight by one less caster than you will use to safely determine load rating.

Extra Heavy Caster Series with Superlast XC Polyurethane Wheels

Are you looking for improved rollability and extra capacity in a resilient tread wheel? If so, Hamilton's 70 durometer polyurethane (Shore D) wheels will deliver. Because the polyurethane is harder than standard 95A poly, these wheels roll more easily and carry up to 30% more capacity - thus the suffix XC, as in extra Capacity! In addition, they effectively repel foreign objects and debris. 1" thick tread chemically bonded to forged steel centers.
