Extra Heavy Duty Casters

Capacity Range: 1600 - 5000 lbs.

  • Swivel Construction
1/2" thick drop forged steel mounting plate; 3/8"x 3" plate steel legs welded inside and outside to forged steel horn base.
  • Kingpin
1" diameter integrally forged with mounting plate guaranteed for life and threaded for 1" diameter lock nut.
  • Main Load Bearing
HPI™ thrust bearing with outside diameter of 5 5/16"; raceways hardened to 58-62HRC and ground to surface finish 16 micro inches.
  • Secondary Load Bearing
1" precision tapered thrust bearing counteracts radial thrust.
  • Axle
3/4" diameter hex head with lock nut.
  • Lubrication Fittings
Ball-check type in swivel assembly and in wheel hubs with tapered or straight roller bearings.
  • Swivel Lock
- 4 Position (-4SL) convert swivel to rigid for straight line steering, robotically welded housing & CNC-milled slots assure long lasting, trouble-free performance.
  • Sealed Swivel Assembly
(-SS) - prolongs caster life in harsh environments.
  • Wheel Bearing Seals
(-DS) - prolong wheel life in harsh environments.
  • Dual Wheel Models
minimize overall height & maximize capacity, see EHD2 Series
  • Custom Engineering
- Hamilton engineers will custom design any caster to meet customer requirements.
 
Hamilton's popular Extra Heavy Duty Casters are widely recognized for their superior performance, wide selection, and reliable service. And now the EHD is even better. The entire EHD Series has been upgraded and now features Hamilton’s new HPI™ Swivel Technology.

The EHD's extra thick hot forgings, guaranteed-for-life integrally forged kingpin and new HPI™ Swivel Technology combine to defy comparison. Yet high volume enables us to price these superior products among the lowest priced casters in their class.
Hamilton Precision and Durability
The enhanced Extra Heavy Duty 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 Extra Heavy Duty (EHD) is backed by Hamilton’s Three Year Product Warranty. Refer to selection table for qualifying wheels.
