Pneumatic Casters: Air-Filled and Foam-Filled for Rough Terrain

These pneumatic casters are air-filled and foam-filled wheels for rough terrain, yards, and outdoor pads. Casters in this collection range from about 250 to 7,700 lb per caster. Foam-filled and flat-free titles on this hub mostly land about 250 to 300 lb. Dual Hamilton air pneumatic builds reach the high end of the page. Soft air or foam treads cushion bumps better than hard iron or phenolic on broken concrete. Soft polyurethane on aluminum (~85 Shore A) or TPR is a different aisle when you need chip clearing on indoor floors. Match single or dual wheel, overall height, and plate size before you order. Pronto stock on some Hamilton titles ships faster. Read the listing for the exact wheel size, overall height, and mount shown. Confirm the load rating printed on the title before you place your order today. Capacities below are per caster unless a listing says set. Air-filled tire aisle: pneumatic air filled. Dual heavy builds: heavy duty dual wheel pneumatic casters.

How to choose

Match plate size and bolt pattern to the cart frame.
Size load per caster (often loaded weight divided by 3 on uneven ground).
Use foam-filled when flats are unacceptable; air-filled when cushion matters most.
Confirm overall height so the cart stays level.

Pneumatic caster questions

Air-filled or foam-filled?

Air-filled rides softer and needs pressure checks. Foam-filled will not go flat from a puncture. Both live on this hub; child pages split the two for narrower searches.

Do Hamilton pneumatics ship fast?

Hamilton Pronto stocked models ship fast when on the shelf. Other Hamilton pneumatic builds can take longer. Read the listing lead note before you order.
