These Hamilton Maxi Duty MD casters fit heavy equipment, dies, molds, and plant carts that move very heavy loads. Casters in this collection range from 3,200 to 23,000 lb per caster. Wheels are up to 12 x 4 and wider in swivel and rigid models. Dual wheel casters split the load over two wheels and swivel with less effort under heavy loads. Wheel options include polyurethane, nylon, phenolic, and forged steel, so match the tread to the floor and the load. Softer polyurethane or soft rubber or TPR tread 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. Read the listing for the exact wheel size, overall height, and mount shown.

Choosing Hamilton Maxi-Duty casters

  1. Load: divide the loaded weight by three for a four-caster cart [S2]. A 10,000 lb caster from this page then suits about 30,000 lb, and the strongest at 23,000 lb about 69,000 lb.
  2. Mount: most Hamilton Maxi-Duty casters use a 8-1/2 x 8-1/2 in top plate; measure bolt hole centers on the old plate and compare.
  3. Floor: on Hamilton Maxi-Duty casters, polyurethane is kinder to tile and finished floors; nylon, forged steel and cast iron roll easier under heavy loads on smooth concrete.
  4. Rig: rigid and swivel Hamilton Maxi-Duty casters are listed.
  5. Heat: among Hamilton Maxi-Duty casters, the highest listed range is -40°F to 320°F on forged steel; check the temperature field on each listing before oven or hot-room use.
