Ball screw linear module DLG42

guideguidedsingle-axis

Overview
DLG series integrates a stepper motor, ball screw and linear guide in a compact assembly to provide precise linear motion and simplified mechanical integration. Guide-supported DLG units reduce external components (couplings, supports) and enable space-saving, high-precision positioning. Size 42 (NEMA 17) is available with 40 mm and 70 mm stroke. A non-guide variant (DRS series) is available as an option.

Dimensional Drawings
External views and dimensional drawings are provided for the DLG42 configuration for reference.

Speed Thrust Curves
Speed–thrust curves are provided for single-stack and double-stack configurations for the 42 mm size.

TEST CONDITION
Testing Voltage: 24 Vdc. Driver model used for reference: DS-OLS2-FPD bipolar chopper driver at rated current (RMS). Motor thrust varies with supply voltage and driver; allow a 50% thrust margin in selection.
