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.

About Metal Caster Wheels

Metal wheels handle the heaviest loads and survive the most abusive environments. Standard on foundries, forging operations, steel mills, and heavy manufacturing where polyurethane can't survive.

How to Choose

1. Material Selection

Forged steel: highest capacity, most abrasion-resistant. Cast iron: medium capacity, lower cost. Semi-steel: budget option for medium loads.

2. Capacity Range

500 to 5,000+ lb per wheel.

3. Floor Compatibility

Metal wheels mark and dent most floors. Use on industrial concrete or steel deck.

4. High-Temperature OK

Metal wheels handle sustained high heat unlike most other wheel materials.
