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.
Superlast XC® models are offered in sizes from 8" x 3" to 12" x 4" and all models are equipped with precision tapered bearings. These are among the highest capacity polyurethane wheels on the market today. They are well suited for towing applications and can be used in many forged steel caster series including Maxi-Duty, Enhanced Precision Super Duty, and kingpinless Super Endurance casters.
