310 Contender Kingpinless Casters

Kingpinless casters replace the central kingpin bolt of a traditional caster with a large sealed raceway. This removes the part most likely to loosen or break under heavy shock and towing, giving higher capacity and much better durability under impact and side loads.

The Albion 310 Contender is a heavy-duty kingpinless caster rated 2,000 to 4,100 lbs each. It is built for towing, platform trucks, and equipment that takes shock and turns under load, where the kingpinless raceway design outlasts standard casters.

Yes. Towing creates side loads and shock that loosen or shear a kingpin bolt. The kingpinless raceway spreads that load and has no bolt to fail, making it the standard for tow lines and heavy industrial moving. The 310 Contender is designed for exactly this.

Each 310 Contender caster carries 2,000 to 4,100 lbs depending on wheel size and material. Divide your total load across all casters and add a safety margin, especially for towing where shock loads spike well above the static weight.

Kingpinless construction removes the central bolt that loosens, bends, or breaks under shock and towing loads. In its place, a hardened, sealed raceway carries the load across a much larger surface, giving higher capacity and far better resistance to impact and side loads. For towing, spring-loaded equipment, and heavy carts that get jolted and turned under load, kingpinless is the proven choice, and the 310 Contender is built for it.

The 310 Contender series carries 2,000 to 4,100 lbs per caster across 6, 8, 10, and 12 inch wheels, in polyurethane, metal, and nylon. Polyurethane protects floors and rolls quietly under heavy loads, while metal and nylon handle the toughest conditions. Swivel and rigid versions let you build a heavy-duty set for towing and platform trucks.
