Kingpinless

We offer a complete line of Kingpinless casters with weight capacities as high as 20,000lbs per caster. All of our Kingpinless casters feature precision machined, heat treated raceways which helps reduce wear and improve swivel rotation. The inner and outer raceways are precisely fit with tight tolerances, eliminating give and “play”, resulting in smoother rotation and longer use life. Our kingpinless design utilizes the swivel bearings to act as load and thrust components to lock the swivel section, and distribute the load, reducing stress on the swivel section.

The 51, 61 and 71 series are made of high alloy steel and offer fully customizable top plates, including size and dimensions, bolt hole type and pattern, and plate thickness. The heavier duty and extreme duty series are made of hot forged C-1045 steel, ensuring maximum strength for your toughest challenges.
