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.

Machined Steel Wheel Casters · Maximum Capacity & Durability

This machined steel wheel suits heavy carts that roll on bare concrete or steel plate. Wheels in this collection are rated 2,500 lb per wheel. The listed size is 4 x 2 in. Machined steel rolls with very low effort under load. It is loud and can mark finished floors. Match the bore, hub length, diameter, and tread width before you order. Capacities below are per wheel unless a listing says set. Confirm the load rating printed on the title before you order. Measure the old wheel or caster before you buy. Read the listing for the exact wheel size, overall height, and mount shown. Verify the stem or plate matches your old unit before you buy. Check the floor type and the heaviest load the cart will carry before you choose. Verify the bore and hub length match your axle before you buy. Steel wheel aisle: steel wheels. Heavy duty hub: heavy duty casters.

Machined Steel Wheel Casters: buying guide

Machined solid steel is the top of the metal-wheel range — the maximum weight capacity, impact strength, and durability of any caster wheel. Where ductile and forged steel reach their limits, machined steel keeps going. The spec for the most extreme metal-wheel applications: foundry, forge, steel mill, and rail.
