This dual-wheel series version of the Maxi-Duty Caster addresses the problem of how to restrict overall height while at the same time provide adequate carrying capacity on resilient tread wheels. Dual Wheel Casters also improve stability and swivel more easily than wider-face single wheels because differential action reduces the “scrubbing” effect of soft treads against the floors. The series still touts its “precision” feature indicating that both the secondary thrust bearing and the main load bearing are precision-made, and yet the new HPI™ Swivel Technology is now a standard feature in this dual wheel series providing smoother swiveling and longer life.
For dual wheel casters in use with lighter duty applications, see EHD2 Series.
The enhanced Maxi-Duty Dual Wheel 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.
The Maxi-Duty Dual Series (MD) is backed by Hamilton’s Three Year Product Warranty. Refer to selection table for qualifying wheels.
