Pneumatic — GSE Capacity up to 8,400 lbs

Hamilton Pneumatic GSE Caster Series Comparison

Hamilton pneumatic GSE casters run air-filled tires on steel rims for outdoor ground support, flightline, and gravel-yard service. Larger tires and higher inflation carry more load over rougher ground, so size the tire to your terrain and load and inflate to the rated pressure.

Series / Config Size Capacity Wheel Best For
Heavy Pneumatic GSE 16" tire up to 8,400 lb Air-filled pneumatic tire on steel rim Heaviest GSE dollies, flightline transport
Standard Pneumatic GSE 13" tire up to 5,500 lb Air-filled pneumatic tire on steel rim Outdoor ground support, gravel yards
Medium Pneumatic 10" tire up to 3,000 lb Air-filled pneumatic tire on steel rim Transition surfaces, mixed indoor and outdoor
Light Pneumatic 8" tire up to 1,400 lb Air-filled pneumatic tire on steel rim Light outdoor carts, uneven pavement

How to Choose

1. Capacity at a 25% Margin

Add cart weight plus payload, divide by the number of casters, then add 25%. Pneumatic capacity is tied directly to tire size and inflation pressure, so a correctly sized but under-inflated tire will not carry its rating. The heavy config reaches up to 8,400 lb per caster on a 16" tire at rated pressure.

2. Wheel and Tire

Every config in this line is an air-filled pneumatic tire on a steel rim, and the air cushion is the point. It absorbs shock from gravel, cracked pavement, and ramp transitions that would stop or jar a hard wheel, and larger-diameter tires roll over bigger obstacles and bridge wider seams.

3. Mount Type and Tire Pressure

Verify the top plate and bolt pattern against your equipment, and account for the larger swing radius of a big pneumatic swivel. Set and maintain the tire to its rated pressure, because both the load rating and the ride depend on it; an under-inflated tire runs hot, loses capacity, and wears the sidewall.

4. Environment

Pneumatic GSE casters are built for outdoor flightline, gravel and unpaved yards, and surfaces that change between concrete and rough ground. The air tire is the right answer when terrain is uneven and impacts are unavoidable, keeping aerospace ground support and defense yard loads moving where a solid wheel cannot.

Engineer Tip: The load rating on a pneumatic tire is only valid at its rated inflation pressure. A 16" GSE tire run at half pressure can lose much of its capacity, run hot, and fail at the sidewall, so put air-tire carts on a pressure-check schedule like a trailer. Call 844-439-4335 and we will confirm the right pressure and tire for your load and terrain.

Frequently Asked Questions

What is a pneumatic GSE caster?

A pneumatic GSE caster uses an air-filled tire on a steel rim, like a vehicle tire, mounted in a caster rig for outdoor ground support equipment. The air cushion absorbs shock from gravel, cracked pavement, and ramp transitions that would jar a hard wheel. Hamilton builds them up to 8,400 lb per caster.

What is the highest capacity pneumatic GSE caster?

The Hamilton pneumatic GSE line reaches up to 8,400 lb per caster on a 16" air-filled tire at rated pressure, and we cross-reference heavier dollies. Call 844-439-4335 with your loaded weight, terrain, and frame details and we will match the tire and rig.

How much air pressure do these tires need?

Each pneumatic tire has a stamped rated inflation pressure, and the load capacity is only valid at that pressure, so run it at the rated PSI and check it on a schedule. Under-inflation loses capacity, runs the tire hot, and wears the sidewall. Call 844-439-4335 for the correct pressure.

Can pneumatic casters be used outdoors?

Yes, outdoor service is exactly what they are for. They are built for flightline, gravel and unpaved yards, and transition surfaces, where the air tire bridges seams and absorbs impacts a hard wheel cannot, and are commonly specified for aerospace ground support and defense yard transport.

What size tire do I need?

Match tire diameter to the roughest surface the caster crosses: larger tires roll over bigger obstacles and bridge wider seams, smaller tires suit lighter carts on uneven pavement. Tire size also sets capacity, from about 1,400 lb on an 8" tire to 8,400 lb on a 16" tire. Give us your terrain and load and we will size it.

Are these casters made in the USA?

Yes. Hamilton Caster has manufactured in Hamilton, Ohio since 1907, and the pneumatic GSE line is built there. CasterHQ is a Hamilton authorized distributor shipping from Mansfield, Texas.
