Superlast®XC 		Are you looking for improved rollability and extra capacity in a resilient tread wheel?  If so, Hamilton's new 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.  Hamilton furnishes this new poly in two wheel configurations: 1/2" thick tread chemically bonded to cast iron centers (Duralast XC ® ) and 1" thick tread chemically bonded to forged steel centers (Superlast XC ® ). Duralast XC ® wheels (bottom chart) have precision ball bearings in all sizes from 4" x 2" to 12" x 3".  In towing applications, Hamilton recommends precision tapered bearings which are available in all 3" wide models.  These wheels can also be mounted in the popular Workhorse, Heavy Service, Champion, and kingpinless Endurance series.

Superlast XC® models (top chart) 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, Precision Super Duty, and kingpinless Super Endurance casters.
