All measurements indicate the wheel diameter by the tread width.

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.

Plate dimensions shown are overall mounting plate size.
When replacing existing casters, select the closest plate size and verify bolt-hole compatibility.
BHP = Bolt Hole Pattern, shown under each plate.

12" x 3" Polyurethane Wheels

Diameter: 12 inCapacity: up to 2,800 lb
12" x 3" Polyurethane Wheels for warehouse carts on epoxy and smooth concrete. Catalog chips cover wheel diameters 12 in, polyurethane treads, and industrial frames. When floors see chemicals or washdowns, prefer sealed bearings and non-absorbent wheel compounds. Match bolt-hole spacing or stem diameter to the frame before you standardize a fleet. These heavy-duty options cover everyday warehouse carts on epoxy and smooth concrete without jumping to extreme forged series.

2 options in this exact size and spec. See all casters by load capacity and mount type › or call 844-439-4335 for a cross-reference.
