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.
Load Rating: 20000 lbs
Diameter: 6 to 18 inches
Width: 3.00 to 5.00 inches
Swivel Section: Constructed of hot forged C-1045 steel, the single ball race design features 7/8 inch diameter load/thrust ball bearings in a 7 inch diameter precision machined raceway.
Load Rating: 10000 lbs
Diameter: 6 to 12 inches
Width: 2.50 to 4.00 inches
Swivel Section: The yoke and top plate of this caster are manufactured by a drop forged process using C-1045 steel. The swivel section is made of a top plate and yoke base that features a precision machined 4 inch single ball bearing and configuration load/thrust raceway (kingpinless style). This raceway design actually places the ¾ inch diameter load/thrust ball bearings in shear load, locking the swivel section together. There is a mechanical shield to protect contamination of the swivel section.
