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.














Hamilton's Series M offers one of the industry's most comprehensive lines of metal wheels. Renowned for durability, these wheels are predominantly cast iron, with select sizes in sintered iron, catering to a wide range of industrial needs.
We have upgraded our most popular metal wheel sizes in the last three years. Now featuring larger hubs and reduced scrap metal content, our wheels stand as a testament to high-quality, long-lasting metal wheels in the industry.
All metal wheels over 5" diameter come equipped with lubrication fittings in the hubs. For smaller sizes, we recommend lube axles to ensure smooth operation and extended service life.
