10″ x 3″ Casters · 800 to 8,200 lb · Polyurethane, Cast Iron & Nylon

These 10 x 3 in casters and wheels rebuild heavy carts, stands, and plant trucks that need a wide 10 in tread. Casters in this collection range from about 280 to 13,100 lb per caster. Bare 10 x 3 wheels on the same aisle reach about 34,000 lb per wheel on forged and Duralast titles. Live SEO once said 800 to 8,200 lb. Active dual-wheel Nylast and forged titles push the caster band higher. Wheel materials include polyurethane (poly or urethane), nylon, cast iron, rubber, and forged steel. Soft polyurethane on aluminum (~85 Shore A) or TPR is the better pick when the floor has chips or grit. Most plates land near 5-1/4 x 7-1/4 in on common series. Choose swivel casters when the cart must turn in place, rigid casters for straight travel, and add a brake when the cart needs to stay put. Capacities below are per caster unless a listing is a bare wheel.

Choosing 10 x 3 in casters and wheels

Load: divide the loaded weight by three for a four-caster cart [S2]. A 4,100 lb caster from this page then suits about 12,300 lb, and the strongest at 8,200 lb about 24,600 lb.
Mount: most 10 x 3 in casters and wheels use a 5-1/4 x 7-1/4 in top plate; 4-1/2 x 6-1/4 in and 4-1/2 x 6-1/2 in plates are listed too; match the bolt holes on your frame to the plate before ordering.
Floor: on 10 x 3 in casters and wheels, polyurethane and rubber are kinder to tile and finished floors; cast iron, nylon, steel, phenolic and forged steel roll easier under heavy loads on smooth concrete.
Rig: swivel and rigid 10 x 3 in casters and wheels are listed, with face contact brake and side lock brake options.
Heat: among 10 x 3 in casters and wheels, the highest listed range is up to 800°F on cast iron; check the temperature field on each listing before oven or hot-room use.
