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 6-1/4Bolt holes: 2-7/16 x 4-15/16 slotted to 3-3/8 x 5-1/4Diameter: 12 inTread: 3 inCapacity: up to 3,500 lb

Match a 4-1/2 x 6-1/4 top plate when bolting casters under warehouse carts on epoxy and smooth concrete. You will see wheel diameters 12 in, polyurethane and steel treads, and capacities 3,500 lb across the SKUs listed below. Match bolt-hole spacing or stem diameter to the frame before you standardize a fleet. 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.
