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.

Match a 5-1/4 x 7-1/4 top plate when bolting casters under warehouse carts on epoxy and smooth concrete. Expect wheel diameters 8 in, polyurethane treads, and capacities 2,500 lb. Size capacity from the heaviest corner load with shock margin, and keep overall height consistent across the set. Larger plates spread bolt stress on thick frames under continuous tow abuse. Match bolt-hole spacing or stem diameter to the frame before you standardize a fleet.
