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.

6" x 2" Phenolic Casters

Diameter: 6 inTread: 2 inCapacity: up to 1,200 lb
Phenolic casters here serve bake carts, metalworking fixtures, and debris-heavy floors. You will see wheel diameters 6 in, phenolic treads, and plate-mount frames across the SKUs listed below. Size capacity from the heaviest corner load with shock margin, and keep overall height consistent across the set. Use kingpinless or heavy plate series when shock loads keep shearing kingpin races. These medium-duty options cover everyday bake carts, metalworking fixtures, and debris-heavy floors without jumping to extreme forged series.
