LKM / LKX Servo linear actuator “combined”

Universal linear actuator with roller screw spindle and servo motor on-top.slg-alle

  • Available stroke from 20 mm to 1225 mm
  • Embodiments of the roller screw spindle:
    • LKM = standard roller screw spindle
    • LKX = high capacity roller screw spindle
  • Position encoder system resolver or absolute encoder

 

Planetary roller screw spindle
In comparison to ball screw spindles (BSS) the roller screw spindle has a lot more contact points. Thus, considerably higher loads can be transmitted with greater rigidity.

  • Advantages:
    • compact dimensions
    • High forces and velocities
    • Long lifetime (about 15x to BSS)

 

LIM / LIX Servo linear actuator “integrated”

Compact linear actuator with inverted roller screw spindle and integrated hollow shaft motorgsx

  • Available stroke, depending on the version from 76 mm to 610 mm
  • Embodiments of the roller screw spindle:
    • LIM = standard roller screw spindle
    • LIX = high capacity roller screw spindle
  • Position encoder system resolver or absolute encoder

 

Inverted planetary roller screw spindle
In the inverted construction, the spindle nut rotates instead of the spindle. In the integrated linear drive LIM / LIX this rotational movement is initiated by the rotor of the servo motor.

  • Characteristics:
    • Shorter construction through hollow shaft motor
    • Compact, fully integrated design
    • Spindle must be secured against rotation!
