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.

Capacity: up to 7,700 lb

This collection gathers industrial casters used on tow-line carts and AGV fixtures. Expect polyurethane treads and capacities 7,700 lb. Harder poly rolls easier on smooth epoxy; softer poly cushions vibration on uneven slabs. For dual-wheel or wide treads, check fork clearance and swivel radius in tight aisles. These heavy-duty options cover everyday tow-line carts and AGV fixtures without jumping to extreme forged series.
