Heavy Duty Ground Support Casters
Series 7500 - Cap. to 4,200 lbs.

#S-7516-SPRT Swivel

Hamilton's new 7500 Series is the ultimate marriage of a truly heavy duty semi-pneumatic tire with Hamilton’s premium forged steel swivel caster technology. This new series is ideally suited for heavy duty ground support applications. Available in four sizes, from 14" x 4" to 21" x 6", all wheels are equipped with 1 1/4" precision tapered roller bearings making them well suited for Ground Support towing applications.

The tires 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.
