20DBM-L High Power Stepper Linear Actuator

High Power Stepper Linear Actuator

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 patent pending pre-load design support higher load capacity & repeatability.
