Forward and reverse lead screw linear module: one lead screw, two sliders, perfectly symmetrical. Engineered for self-centering, clamping, or synchronized spreading without dual actuators. The left- and right-hand threads on a single screw drive two sliders in opposite directions with exact mechanical symmetry—ideal for part centering, vial capping, solar cell alignment, or adaptive gripper bases. ✅ Zero electronic sync needed – motion is built into the screw ✅ Saves 40% space vs. dual-axis solu
