Discover the appropriate spindle for your application

The parameters and requirements for the application of your lifting gear are crucial when choosing either a trapezoidal thread or ball screw, especially concerning the following:

  • Duty cycle
  • Repitition accuracy and positioning accuracy
  • Stroke speed
  • Stat. / dyn. loading (Hold load in position or move)
  • Service life and maintenance

Characteristics_Trapezoidal thread or ball screw

Functionality | Rotating and translating spindle

R-Screw | rotating
The spindle is fixed to the worm wheel and rotates with it. The nut therefore moves up and down.

S-Screw | translating
The worm wheel has an internal thread and transforms rotary motion into linear movements as long as the spindle is prevented from rotating.
