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 heavy warehouse carts, die carts, and plant fixtures. Expect wheel diameters 8, 10, 12 in, cast iron and steel treads, and capacities 2,500 to 3,000 lb. When floors see chemicals or washdowns, prefer sealed bearings and non-absorbent wheel compounds. Larger plates spread bolt stress on thick frames under continuous tow abuse. These heavy-duty options cover everyday heavy warehouse carts, die carts, and plant fixtures without jumping to extreme forged series.
