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.

Caster T-Nuts & Sockets for Stem Casters

Tread: 1-1/2 inStem: threaded

Industrial tread compounds casters here serve warehouse carts, racks, and everyday plant fixtures. You will see threaded-stem and grip-ring stem frames across the SKUs listed below. Confirm stem length and thread pitch on stem mounts so the shoulder seats flush in the boss. For dual-wheel or wide treads, check fork clearance and swivel radius in tight aisles. These medium-duty options cover everyday warehouse carts, racks, and everyday plant fixtures without jumping to extreme forged series.
