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.
