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 2" 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. You will see wheel diameters 4 in, polyolefin treads, and capacities 300 to 900 lb across the SKUs listed below. Confirm stem length and thread pitch on stem mounts so the shoulder seats flush in the boss. Replace worn corners in matched sets when possible so the cart tracks straight under load.
