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 Metal Wheels, predominantly cast iron and some sintered iron, are recognized for their extensive range and reliability. With recent enhancements, these wheels now feature larger hubs and reduced scrap metal content, representing the pinnacle of durability and quality in the metal wheel industry.
All metal wheels over 5" diameter are equipped with lubrication fittings in the hubs, ensuring longevity and ease of maintenance. For wheels smaller than 5", lube axles are recommended. Note that some non-standard bores within the indicated range may incur extra charges, and close tolerances are always treated as special requests, quoted upon receipt of specific details.
Hamilton is committed to meeting unique requirements and offers customization for non-standard bores. Our commitment to precision and quality ensures that every wheel aligns with the highest industry standards, delivering unmatched performance and durability.
