New EHS Series featuring HPI™ Swivel Technology w/ Polysoft® Wheel.
|  | The enhanced Extended Service Series now features Hamilton’s Precision Integrated HPI™ Swivel Technology. This new technology outperforms conventional CNC-machined ball raceways, kingpinless, and unit load bearing swivel constructions.
The new design improves the bearing’s element of contact and more than doubles the number of contact points. The new HPI™ raceways are also 45% harder than conventional hardened raceways and the surface finish is an incredibly smooth 16 micro inches. | | When grueling loads and continuous operations exist, Hamilton's Extended Service Casters with new HPI™ Swivel Technology are the right choice. ES Series Casters are an excellent choice for use on inplant trailers, towline carts or AGV systems. New to this series is a 2" wide wheel offering, ES Series, specifically designed for continuous duty applications that also feature the new HPI™ Swivel Technology. The ES Series is finished with gray enamel and the EHS Series is finished with red enamel.
