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.

Tread: 3, 5 inCapacity: up to 22,800 lb

18" x 5" Rubber Wheels for finished floors and quiet institutional carts. Catalog chips cover rubber treads, industrial frames, and capacities 3,000 to 22,800 lb. Softer treads quiet finished floors; harder compounds last longer on chips, heat, and rough concrete.
