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.

25" x 7.5" Rubber Wheels

Capacity: up to 4,200 lb

25" x 7.5" Rubber Wheels for finished floors and quiet institutional carts. Typical builds show rubber, steel, and pneumatic treads, industrial frames, and capacities 3,800 to 4,200 lb. Replace worn corners in matched sets when possible so the cart tracks straight under load. When floors see chemicals or washdowns, prefer sealed bearings and non-absorbent wheel compounds. These heavy-duty options cover everyday finished floors and quiet institutional carts without jumping to extreme forged series.
