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.

Casters on the 5-1/4 x 7-1/4 plate pattern suit warehouse carts on epoxy and smooth concrete. Expect wheel diameters 6 in, polyurethane and steel treads, and capacities 2,000 lb. Pair swivel and rigid casters for tracking, or use total locks where the cart must park on a grade. Larger plates spread bolt stress on thick frames under continuous tow abuse. These heavy-duty options cover everyday warehouse carts on epoxy and smooth concrete without jumping to extreme forged series.
