This collection holds Heavy Duty casters with Duralast polyurethane, metal and ergonomic polyurethane wheels, built for shop carts, equipment, and material handling carts that move heavier loads. Casters in this collection range from 410 to 2,500 lb per caster. Wheels in this category range from 4 up to 10 inches in diameter with 2 to 3 in tread widths. The collection includes swivel and rigid models. Kingpinless swivels hold up better under shock and repeat loads. Dual wheel casters split the load over two wheels and swivel with less effort under heavy loads. 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. 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 heavy duty casters

Load: divide the loaded weight by three for a four-caster cart [S2]. A 2,000 lb caster from this page then suits about 6,000 lb, and the strongest at 3,000 lb about 9,000 lb.
Mount: most Hamilton heavy duty casters use a 4-1/2 x 6-1/2 in top plate; 4 x 4-1/2 in and 5 x 7 in plates are listed too; check the bolt spacing on your frame against the plate size.
Floor: on Hamilton heavy duty casters, polyurethane and rubber are kinder to tile and finished floors; cast iron, phenolic, nylon and steel roll easier under heavy loads on smooth concrete.
Rig: rigid and swivel Hamilton heavy duty casters are listed.
Heat: among Hamilton heavy duty casters, the highest listed range is -22°F to 750°F on steel; check the temperature field on each listing before oven or hot-room use.
