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 2" Nylon Casters

Capacity: up to 3,000 lb

Nylon casters here serve chemical, food-contact, and washdown carts. Expect nylon treads, industrial frames, and capacities 3,000 lb. Size capacity from the heaviest corner load with shock margin, and keep overall height consistent across the set. Confirm stem length and thread pitch on stem mounts so the shoulder seats flush in the boss. These heavy-duty options cover everyday chemical, food-contact, and washdown carts without jumping to extreme forged series.
