Resin Lead Screws-Resin Nuts

Super-slim miniature actuators, up to 24mm wide and 30mm high (palm-sized).
Low-friction resin lead screws (resin Units) are used, resulting in low operating noise.
Five-phase stepping motors are used, for smooth movement with minimal heat generation.
Lightweight design makes these units ideal for vertical mounting
