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.
UltraGlide EHD is the extra-heavy-duty build of Hamilton's UltraGlide polyurethane — the same low-rolling-resistance, long-life compound, mounted on heavier Extra-Heavy-Duty rigging and rated to 5,000 lb per wheel. It's UltraGlide for applications where the rig has to be as tough as the wheel.
















































Standard UltraGlide pairs the premium wheel with standard rigging. UltraGlide EHD pairs it with Hamilton's Extra-Heavy-Duty (EHD) rig — heavier construction, kingpinless options, built for impact and continuous abuse. You spec EHD when the application punishes the whole caster, not just the wheel: rough floors, drop-loading, sustained high-cycle duty under heavy load.
Heavy tugger-train carts, continuous-duty transfer in foundry and steel-adjacent environments, and any extra-heavy application that still needs polyurethane's floor protection and low rolling resistance. It's the bridge between premium-wheel and heavy-rig — you get both.
Same premium wheel compound. EHD adds Hamilton's Extra-Heavy-Duty rigging — heavier, tougher, built for impact and abuse.
Up to 5,000 lb per wheel. For higher, see Hamilton's heavier kingpinless and Maxi-Duty platforms.
When the rig takes abuse — rough floors, drop-loading, continuous heavy cycling. If only the wheel works hard, standard UltraGlide suffices.
Our US-based caster engineers will match the right build to your load, floor, and application.
