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.

4" x 1.5" Polyolefin Wheels

Diameter: 4 inTread: 1-1/2 inCapacity: up to 900 lb

This collection gathers industrial casters used on warehouse carts, racks, and everyday plant fixtures. Expect wheel diameters 4 in, polyolefin treads, and capacities 400 to 900 lb. Match bolt-hole spacing or stem diameter to the frame before you standardize a fleet. Replace worn corners in matched sets when possible so the cart tracks straight under load. These medium-duty options cover everyday warehouse carts, racks, and everyday plant fixtures without jumping to extreme forged series.
