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.

4" x 3" Polyurethane Casters

Capacity: up to 800 lb

4" x 3" Polyurethane Casters for warehouse carts on epoxy and smooth concrete. You will see polyurethane treads, industrial frames, and capacities 800 lb across the SKUs listed below. Pair swivel and rigid casters for tracking, or use total locks where the cart must park on a grade. When floors see chemicals or washdowns, prefer sealed bearings and non-absorbent wheel compounds.
