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.

Shop polyurethane and nylon replacement wheels when you need a new tread without buying a full caster. Typical builds show wheel diameters 6, 8, 10 in, polyurethane and nylon treads, and industrial frames. Confirm bearing type and axle hardware so the replacement spins freely under load. Keep diameter and tread width the same as the worn wheel to preserve overall height. These heavy-duty options cover everyday chemical, food-contact, and washdown carts without jumping to extreme forged series.
