The below capacity ranges indicate the working (dynamic) load that each caster will support. A safety factor should be included in your formula to determine your required load rating per caster.

W/(C-1)=R W is total weight needed to move. C is total number of casters required. R is ideal load rating, with safety factor built in. Divide the total load weight by one less caster than you will use to safely determine load rating.

Plate sizes: 4-1/2 x 6-1/2Diameter: 3-1/4 inTread: 2 inCapacity: up to 1,400 lb

Casters on the 4-1/2 x 6-1/2 plate pattern suit bake carts, metalworking fixtures, and debris-heavy floors. Catalog chips cover wheel diameters 3-1/4 in, phenolic treads, and capacities 1,100 to 1,400 lb. Pair swivel and rigid casters for tracking, or use total locks where the cart must park on a grade. For dual-wheel or wide treads, check fork clearance and swivel radius in tight aisles.
