Maxi-Duty Casters
Series MD - Cap. to 23,000 lbs.
#S-MD-84FST Swivel w/ Forged Steel Wheel


Maxi-Duty Rigid models feature reinforced 3/8” x 5” plate steel legs, continuously welded inside and outside to 1/2" thick mounting plates.

The enhanced Maxi-Duty 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.
Move over 10 tons on Hamilton’s top-of-the-line Maxi-Duty Casters, designed and built for the toughest applications including shipbuilding, manufactured housing, automotive and aerospace. Long life and dependable service are assured now more than ever with Hamilton's new HPI™ Swivel Technology. The new technology is a significant upgrade from conventional ball raceways or unit load bearings and provides an even stronger platform to support Hamilton’s three year product warranty. All forged steel wheels are machined with a slight crown to enhance rollability and swiveling.
