Hamilton Caster has improved the swivel technology on its heavy-duty forged steel casters with capacities from 600 lbs. to 23,000 lbs. The new design is intended to improve the bearing’s element of contact and more than double the number of contact points. Also, the new raceways are 45% harder than conventional hardened raceways, and the surface finish is smoother. The swivel technology is standard on most casters and can be added as an option on others. 888-699-7164, HamiltonCaster.com.
