20DBM-K High Power Stepper Linear Actuator
Portescap
High Power Stepper Linear Actuator
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 patent pending pre-load design support higher load capacity & repeatability.
