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.

8" x 4" Polyurethane Casters

This collection gathers industrial casters used on warehouse carts on epoxy and smooth concrete

Typical builds show polyurethane treads. Match bolt-hole spacing or stem diameter to the frame before you standardize a fleet. Softer treads quiet finished floors; harder compounds last longer on chips, heat, and rough concrete. These medium-duty options cover everyday warehouse carts on epoxy and smooth concrete without jumping to extreme forged series.
