This collection holds High-Heat Casters with metal and forged steel wheels, built for heavy equipment, dies, molds, and plant carts that move very heavy loads. Casters in this collection range from 260 to 6,250 lb per caster. Wheels in this category range from 3 up to 12 inches in diameter with 1 to 4 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. Metal wheels roll with low effort and handle debris and heat. They are loud and can mark finished floors. Forged steel wheels carry very heavy loads and handle impact, debris, and heat. They are loud and will mark finished floors. Choose swivel casters when the cart must turn in place and rigid casters for straight travel. Forged steel aisle: forged steel casters. Wheel hub: replacement wheels.

Choosing high heat casters

  1. Load: divide the loaded weight by three for a four-caster cart [S2]. A 1,400 lb caster from this page then suits about 4,200 lb, and the strongest at 5,500 lb about 16,500 lb.
  2. Mount: most high heat casters use a 4 x 4-1/2 in top plate; 2-1/2 x 3-5/8 in and 4-1/2 x 6-1/2 in plates are listed too; measure bolt hole centers on the old plate and compare.
  3. Floor: on high heat casters, polyurethane is kinder to tile and finished floors; steel, cast iron, nylon, stainless steel and forged steel roll easier under heavy loads on smooth concrete.
  4. Rig: rigid and swivel high heat casters are listed.
  5. Heat: among high heat casters, the highest listed range is up to 750°F on steel; check the temperature field on each listing before oven or hot-room use.
