This collection holds 16 in x 4 in Casters with polyurethane, poly on iron and rubber wheels, built for heavy equipment, dies, molds, and plant carts that move very heavy loads. Casters in this collection range from 1,200 to 22,800 lb per caster. Wheels in this category are 16 inches in diameter with 4 in tread width. The collection includes swivel, rigid, and brake models. Kingpinless swivels hold up better under shock and repeat loads. Polyurethane (poly or urethane) treads are quiet, floor safe, and resist water and many chemicals. Rubber wheels are quiet, cushion the load, and protect floors. Softer poly or TPR is the better pick when the floor has chips or grit. Plate and stem mounts are listed on each product so you can match bolt pattern or stem size 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 16 x 4 in wheels

  1. Load: divide the loaded weight by three for a four-wheel cart [S2]. A 5,500 lb wheel from this page then suits about 16,500 lb, and the strongest at 15,500 lb about 46,500 lb.
  2. Mount: most 16 x 4 in wheels 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 16 x 4 in wheels, polyurethane and rubber are kinder to tile and finished floors; phenolic and cast iron roll easier under heavy loads on smooth concrete.
  4. Rig: swivel and rigid 16 x 4 in wheels are listed.
