8 x 3 Casters and Wheels

This collection holds 8 in x 3 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 250 to 10,000 lb per caster. Wheels in this category are 8 inches in diameter with 3 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.

Questions

Caster capacity or wheel capacity?

Complete caster titles top out about 22,400 lb each on dual forged builds. Bare wheels can list to about 23,000 lb with no yoke rating.

Single or dual wheel?

Duals share load on one yoke and are rated per caster for that assembly. Singles on this size commonly top lower than the dual extreme.
