Hamilton’s full Pneumatic caster offerings are available in medium duty cold forged casters or in heavy duty forged steel casters. The forged steel line is offered in multiple finishes, with single-wheel and dual-wheel configurations and in sizes from 8” to 25” diameter. Whether you need to mount them on boat dollies, line-striping equipment, shipping containers, airport luggage trailers or even golf ball collectors, there is a full pneumatic caster solution available for you—and most likely PRONTO®. Foam filling is available in all tire sizes.
