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 AEZFWH is the AEZ-platform spring-loaded Workhorse caster — up to 1,200 lb per caster, built for towed equipment and impact-prone routes that need shock suspension without heavy-platform cost. It's the medium-duty member of Hamilton's AEZ spring-loaded family.
















Hamilton's AEZ spring-loaded series comes in tiers built on different rig bases: the AEZFFM Forge Master is the heavy end (2,775 lb), while the AEZFWH (Workhorse base) and AEZFHS (Heavy Service base) cover the 1,200 lb medium-duty range. The AEZFWH is the one to spec when you need genuine spring suspension on towed or impact-prone equipment but the load sits in medium-duty territory.
Towed carts and tow-line trailers carrying medium loads, equipment on rough-floor routes, and material-handling rigs that take repeated impact. The spring absorbs the start-stop coupling shock and floor-seam hits that, on a rigid caster, fatigue both the load and the equipment over time.
AEZ-platform spring-loaded Workhorse caster — to 1,200 lb per caster, the medium-duty member of Hamilton's AEZ spring-loaded family.
Both are spring-loaded Workhorse-based casters around 1,200 lb. The AEZ platform is a distinct Hamilton spring-loaded family — confirm the exact fit for your equipment.
Towed or impact-prone routes — the spring absorbs coupling shock and floor-seam hits that fatigue rigid-caster equipment.
Our US-based caster engineers will match the right build to your load, floor, and application.
