Lead Screw Motor Assembly

Lead Screw Linear Actuator Motor Assemblies

Lead screw assemblies with NEMA 08, 11, 14, 17, or 23 motors deliver high torque and precision, offering multiple lead screw and nut combinations per frame size. Available in captive and non-captive designs, they include angular contact bearings inside the motor housing to support the screw, ensuring enhanced thrust, durability, and minimal runout, with preloaded bearings eliminating axial play, which refers to unwanted movement along the axis of the screw that can affect precision. Optional "Smart Motor" Technology offers 50% more torque to dramatically reduce cycle times

Lead screw assemblies with NEMA 08, 11, 14, 17, or 23 motors deliver high torque and precision, offering multiple lead screw and nut combinations per frame size. Available in captive and non-captive designs, they include angular contact bearings inside the motor housing to support the screw, ensuring enhanced thrust, durability, and minimal runout, with preloaded bearings eliminating axial play, which refers to unwanted movement along the axis of the screw that can affect precision. Optional "Smart Motor" Technology offers 50% more torque to dramatically reduce cycle times


  • Five frame sizes: NEMA 08/11/14/17/23
  • Each frame size motor has different standard lead screw and nut combinations
  • Larger bearings increase thrust capacity and longer life
  • Preload on bearings eliminates axial play
