- Ultra-fine positioning: this 2-phase 4-wire stepper motor delivers 0.025 mm per-step resolution (18° step) for precise control. The 0.5 mm gradient crepe provides a smooth linear travel of 34 mm. - All-metal planetary gears: metal gear reduction system with 21Ω phase resistance for consistent torque. Compact 20 mm diameter design fits space-constrained applications such as 3D printer extruders or CNC router accessories. - Compact industrial design: 45 mm screw length and 1.3 inch slider travel. Stainless steel construction supports damp workshop conditions. Suitable for camera sliders and microscope steps. - Long-lasting performance: metal-to-metal gear reduction offers over 50,000 operating cycles and maintains positioning accuracy in vibration-prone environments. Ideal for repetitive tasks in packaging machines and textile equipment. - Typical uses: in 3D printer extruders, camera sliders, microscope positioning stages, and repetitive positioning duties in packaging or textile machinery.
