Capacity: up to 6,000 lb
This collection gathers kingpinless casters used on heavy industrial carts that tear up kingpin races. Expect polyurethane, phenolic, and steel treads and capacities 6,000 lb. Use kingpinless or heavy plate series when shock loads keep shearing kingpin races. When floors see chemicals or washdowns, prefer sealed bearings and non-absorbent wheel compounds. These heavy-duty options cover everyday heavy industrial carts that tear up kingpin races without jumping to extreme forged series.

Super Endurance Kingpinless SEC Casters: buying guide

Endurance engineering at heavy capacity

The standard Endurance series proved the concept at 1,000 lb: forged kingpinless construction and heat-treated raceways survive the cycle count of 24/7 operation. The SEC series takes that same engineering and builds it heavy — to 6,000 lb per caster. So now continuous-duty heavy transfer equipment, not just light production carts, can be specified for endurance instead of just capacity.

Where SEC belongs

Heavy tow-line trains in continuous operation, 24/7 transfer carts in foundry and steel-adjacent environments, and any heavy industrial equipment where the duty cycle is constant and a caster failure means a line-down event. The kingpinless raceway distributes load and resists the cornering wear that kills kingpin casters under sustained heavy cycling.

Common questions

What is the SEC series?

Super Endurance Caster — Hamilton's forged kingpinless, heat-treated-raceway endurance engineering scaled to 6,000 lb per caster for heavy continuous duty.

SEC vs the standard Endurance series?

Same endurance engineering. The standard Endurance series tops at 1,000 lb; SEC reaches 6,000 lb for heavy continuous duty.

Why kingpinless for endurance?

The kingpinless raceway distributes cornering load across a full circumference instead of a single shaft — it doesn't develop the play that wears out kingpin casters under sustained heavy cycling.
