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.
