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.
The AEZFFM — AEZ Forge Master — is Hamilton's heaviest spring-loaded caster series, up to 2,775 lb per caster. It builds the spring suspension onto Forge Master rigging, the platform engineered for the heaviest spring-loaded duty: ground-support equipment, heavy tow-line trains, and impact-heavy routes carrying real weight.

















Spring suspension is most often a light-to-medium-duty feature — but heavy ground-support equipment and heavy tow-line trains take serious impact AND carry serious load. The AEZFFM Forge Master answers that: Forge Master rigging engineered for heavy abuse, with the spring suspension built in, rated to 2,775 lb per caster. It's the top of the spring-loaded range.
Aircraft ground-support equipment towed across hangar floors and apron transitions, heavy tow-line trains in continuous operation, and any heavy route where the equipment takes repeated hard impacts. The spring protects the load and the equipment; the Forge Master rigging takes the abuse the spring doesn't.
AEZ Forge Master — Hamilton's heaviest spring-loaded caster platform, to 2,775 lb per caster, built on heavy-duty Forge Master rigging.
It's the heaviest. SPWH (1,200 lb) and SPCH (1,630 lb) cover medium duty; AEZFFM reaches 2,775 lb for heavy spring-loaded applications.
Aircraft ground-support equipment, heavy tow-line trains, and impact-heavy routes that carry real load.
Our US-based caster engineers will match the right build to your load, floor, and application.
