C&K JD3-25S Dovetail stage (Screw type)

JD3-25S is a compact single-axis vertical manual positioning stage with a 25×25mm top platform, manufactured from black anodized aluminum with total weight of 0.12kg. Designed exclusively for Z-axis vertical height adjustment via screw and dovetail transmission, it comes with an integrated side mounting base for direct fixation on equipment frames, commonly deployed for vertical fine tuning of optical lenses, miniature sensors and test fixtures in lab and precision inspection equipment.

Key Performance Features
This vertical stage delivers ±4mm adjustment travel with 0.1mm vernier readable resolution, featuring 40μm platform parallelism and 30μm driving parallelism to keep stable flatness during vertical lifting movement, and its mechanical structure supports 0.5kgf rated load to hold lightweight precision parts; black anodized aluminum construction delivers reliable anti-corrosion and wear resistance for consistent long-term vertical positioning performance under regular working environments.

Cost Effectiveness
Optimized compact vertical structural design simplifies machining processes to lower raw material and production cost compared with customized vertical positioning slides, and its dovetail friction structure requires only regular surface cleaning without costly replacement parts to cut long-run maintenance expense; the integrated fixed side base eliminates users’ extra auxiliary fixture cost for installation, while built-in vernier scale removes additional spending on digital displacement sensors to replace expensive motorized vertical actuators economically for small-stroke vertical fine adjustment applications.
