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.

36" Shelving Units

Capacity: up to 800 lb

This collection gathers plate-mount casters used on warehouse carts, racks, and everyday plant fixtures. You will see capacities 800 lb across the SKUs listed below.
