This collection holds ForgeMaster casters with Duralast polyurethane, metal and rubber wheels, built for heavy equipment, dies, molds, and plant carts that move very heavy loads. Casters in this collection range from 540 to 3,200 lb per caster. Wheels in this category range from 5 up to 10 inches in diameter with 2 to 3 in tread widths. The collection includes swivel and rigid models. Duralast polyurethane treads are quiet, protect floors, and carry heavy loads with low rolling effort. Metal wheels roll with low effort and handle debris and heat. They are loud and can mark finished floors. Rubber wheels are quiet, cushion the load, and protect floors. Soft rubber or TPR is the better pick when the floor has chips or grit. Match plate size, bolt pattern, and overall height before you order. Choose swivel casters when the cart must turn in place and rigid casters for straight travel. Polyurethane aisle: polyurethane casters. Wheel hub: replacement wheels.

Choosing Hamilton ForgeMaster casters

Load: plan on three casters carrying a four-caster cart [S2]; at 2,200 lb each, a common rating here, that is about 6,600 lb, and the 3,200 lb top rating covers about 9,600 lb.
Mount: most Hamilton ForgeMaster casters use a 4-1/2 x 6-1/2 in top plate; 5 x 7 in plates are listed too; measure bolt hole centers on the old plate and compare.
Floor: on Hamilton ForgeMaster casters, polyurethane and rubber are kinder to tile and finished floors; cast iron, phenolic, steel and nylon roll easier under heavy loads on smooth concrete.
Rig: swivel and rigid Hamilton ForgeMaster casters are listed.
Heat: among Hamilton ForgeMaster casters, the highest listed range is -40°F to 320°F on cast iron; check the temperature field on each listing before oven or hot-room use.
