XZ-Series - Extra Heavy Duty Kingpinless Drop Forged (Capacity to 6,000lbs)



  • Hot forged ASTM 1045 steel
  • Eliminated kingpin failure due to severe shock loading
  • Top plate and inner raceway are integrally forged
  • Precision machined and hardened raceway
  • 1/2” diameter HRC 45 steel ball bearings absorb thrust and load
  • 3/4” standard axle
  • Zinc plated
  • Grease fitting in swivel raceway
  • 4 position notches standard


Typical uses for the XZ series include machinery dollies, portable steel storage racks, heavy duty work benches, production fixtures, and anywhere shock loading is anticipated.
