20DBM-K

20DBM-K Captive Linear Actuator Stepper Motor

20DBM-K Linear Actuator Stepper Motor

20DBM-K

The 20DBM-K high resolution captive stepper linear actuators are tailored for demanding applications that need smaller move increments and finer positioning.With 7.5 deg step angle,these linear actuators can deliver a high linear force up to 50N. Larger ball bearings with proprietary pending pre-load design support higher load capacity & repeatability.

Product Highlights

  • Neodymium magnet for high performance
  • Compact design
  • Winding possibilities
  • Larger ball bearings
  • Improved heat dissipation
  • Optimized preload

Customization Available

  • Adaptor / extension tips
  • Cable or terminal outputs
  • Coil modifications - resistance and inductance
  • Longer / shorter stroke lengths
  • Mounting plate
  • Preload / axial play
  • Sleeve or ball bearings
