Choosing 5 x 1-1/4 in casters and wheels

Load: divide the loaded weight by three for a four-caster cart [S2]. A 325 lb caster from this page then suits about 975 lb, and the strongest at 350 lb about 1,050 lb.
Mount: most 5 x 1-1/4 in casters and wheels use a 2-3/8 x 3-5/8 in top plate; 3-1/8 x 4-1/8 in and 2-1/2 x 3-5/8 in plates are listed too; match the bolt holes on your frame to the plate before ordering.
Floor: on 5 x 1-1/4 in casters and wheels, polyurethane, rubber and TPR are kinder to tile and finished floors; polyolefin, phenolic, nylon and semi-steel roll easier under heavy loads on smooth concrete.
