Hamilton Heavy Duty Ground Support Casters

Capacity Range: 1,500 – 4,200 lbs.

Hamilton's 7500 Series is the ultimate marriage of a truly heavy duty solid pneumatic tire with Hamilton’s premium forged steel swivel caster technology. This series is ideally suited for heavy duty ground support applications. Available in six wheel diameters from 10" x 4" to 21" x 6", all wheels are equipped with 1" or 1 1/4" precision tapered roller bearings making them well suited for Ground Support towing applications.

The 16", 18", and 21" wheels are comprised of three tread sections: a firm, stable base compound for strong rim adhesion; a very resilient middle section to dampen the shock of uneven rolling surfaces; and a tough low rolling resistance tread to reduce energy consumption. The result is a soft ride that compares with full pneumatic tires, but with much higher capacities than their air-filled cousins.

The 12" and 14" wheels are comprised of two tread sections. The same stable base found on the other wheels for strong rim adhesion combined with a tough abrasion resistant outer tread compound.
