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.

Superlast XC

Diameter: 8, 10, 12 inTread: 4 inCapacity: up to 7,800 lb
Polyurethane and steel casters here serve warehouse carts on epoxy and smooth concrete. Expect wheel diameters 8, 10, 12 in, polyurethane and steel treads, and industrial frames. Use kingpinless or heavy plate series when shock loads keep shearing kingpin races. Replace worn corners in matched sets when possible so the cart tracks straight under load. These heavy-duty options cover everyday warehouse carts on epoxy and smooth concrete without jumping to extreme forged series.
