Magmamax Series High Temperature Extra Heavy Duty

MagmaMax™ Series Extra Heavy Duty Casters

Capacity Range: 1,000 – 9,000 lbs. Temperature Range: -22 – 750° F

The new MagmaMax Series represents Hamilton’s highest load-rated casters for high heat applications. With a max load rating of 9000 lbs. and a max heat rating of 750°F, the MagmaMax is well-suited for the heaviest loads in the hottest environments among industrial applications.

Massive autoclaves and product finish systems in heavy manufacturing, energy, and aerospace industries are just a few applications these casters are designed for.

The MagmaMax series are essentially Hamilton’s proven and reliable Super Endurance Series and a new Kingpinless Maxi-Duty (MDK) Series with the same forged steel swivel construction but equipped with special high heat grease in the raceways, special high heat precision shielded ball bearings in the wheels, and painted black.
