20DBM-L

20DBM-L Non-captive Linear Actuator Stepper Motor

20DBM-L Linear Actuator Stepper Motor

20DBM-L

The 20DBM-L high resolution non captive stepper linear actuators are tailored for demanding applications that need smaller move increments and finer positioning. With 7.5 deg step angle, these high power 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
