10″ x 4″ Casters - EPSD, Maxi-Duty, 18,000 lb

This collection holds 10 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 750 to 28,800 lb per caster. Wheels in this category are 10 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 10 x 4 in casters and wheels

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 28,800 lb about 86,400 lb.
Mount: most 10 x 4 in casters and wheels use a 8-1/2 x 8-1/2 in top plate; 6-1/2 x 7-1/2 in and 6-1/4 x 7-1/2 in plates are listed too; measure bolt hole centers on the old plate and compare.
Floor: on 10 x 4 in casters and wheels, polyurethane and rubber are kinder to tile and finished floors; forged steel, steel, nylon and phenolic roll easier under heavy loads on smooth concrete.
Rig: swivel and rigid 10 x 4 in casters and wheels are listed.
Heat: among 10 x 4 in casters and wheels, the highest listed range is up to 800°F on forged steel; check the temperature field on each listing before oven or hot-room use.
