Hamilton kingpinless casters carry up to 17,500 lb per caster with no central kingpin to shear or loosen under shock. Forged steel, UltraGlide polyurethane, and Duralast wheels suit towlines, manual heavy transport, and high-shock service.
| Series / Config | Size | Capacity | Wheel | Best For |
|---|---|---|---|---|
| Kingpinless, forged steel | 8"–12" | up to 17,500 lb | Forged steel | High-shock towlines, hard floors, debris |
| Kingpinless, UltraGlide poly | 8"–10" | up to 12,000 lb | UltraGlide polyurethane on steel core | Manual transport, floor protection, lower push |
| Kingpinless, Duralast | 6"–10" | up to 10,000 lb | Duralast polyurethane | Cut and chip resistance, mixed-debris floors |
| Kingpinless, forged steel, compact | 6"–8" | up to 8,000 lb | Forged steel | Tight footprint, repeated impact |

Add the static load and payload, divide by the load-bearing casters, then add 25% margin over the worst-case caster. On towlines, shock and floor transitions concentrate load on one corner at a time. Size each caster for that worst case so the swivel runs well inside its rating.
Forged steel reaches the full 17,500 lb and tolerates chips and impact on hard floors. UltraGlide polyurethane protects finished floors and lowers push force at moderate capacity. Duralast resists cuts and chips on mixed-debris floors. Choose steel for max capacity and impact, poly for floor protection, Duralast for cut resistance.
Top plate is standard and the kingpinless design routes load through a large hardened raceway instead of a single bolt. That is the reason to specify it on high-shock service, the raceway spreads impact that would loosen or shear a conventional kingpin. Confirm the plate bolt pattern and deck thickness match the rating.
Automotive, heavy plant, and defense floors expose casters to repeated impact and debris. Forged steel and Duralast handle chips and shock better than soft polyurethane. The sealed kingpinless raceway keeps grit out of the swivel, which extends life on dirty floors where a kingpin would wear and develop play.
It is a heavy-duty caster that carries swivel load through a large hardened raceway instead of a central kingpin bolt. Removing the kingpin removes the single point that loosens or shears under repeated shock, so the swivel holds up on towlines and high-impact service. Hamilton rates it up to 17,500 lb per caster.
Up to 17,500 lb per caster on the forged steel configuration. Polyurethane and Duralast configurations rate lower because the tread limits the load. Size each caster to the worst-case corner load with 25% margin, especially on shock-prone towlines.
Forged steel, UltraGlide polyurethane on a steel core, and Duralast polyurethane. Forged steel carries the most and tolerates impact and debris. UltraGlide protects floors and lowers push force. Duralast resists cuts and chips on mixed-debris floors.
Towlines, manual heavy industrial transport, and high-shock service are the core applications. The series suits automotive, heavy plant, and defense floors where repeated impact would loosen a conventional kingpin. It is the standard choice anywhere the swivel sees sustained shock.
Yes. Hamilton has manufactured casters in Hamilton, Ohio since 1907. Kingpinless casters are built domestically, which keeps custom configurations and replacements available and supports automotive and defense supply-chain requirements.
Provide the worst-case load per caster, floor condition, shock level, and mount plate requirement. We match those to the correct wheel and capacity tier and confirm the Hamilton part. Call 844-439-4335 or send your existing caster spec for a direct cross-reference.
