Back to Casters

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.

Plate sizes: 4 x 4, 4 x 4-1/2Bolt holes: 2-5/8 x 3-3/8 slotted to 3 x 3Diameter: 4, 5, 6 inTread: 1-1/2 inCapacity: up to 850 lb
4 x 4-1/2 inch top-plate casters for warehouse carts on epoxy and smooth concrete. Catalog chips cover wheel diameters 4, 5, 6 in, polyurethane, polyolefin, and rubber treads, and capacities 280 to 850 lb. Harder poly rolls easier on smooth epoxy; softer poly cushions vibration on uneven slabs. When floors see chemicals or washdowns, prefer sealed bearings and non-absorbent wheel compounds.
