Minimal Ultra-Light Entry Manual Stage (JD3-44S Compact Dovetail Light-Load Model)

Engineered for lightweight embedded integration and low-budget light-duty alignment tasks, the JD3-44S manual positioning stage adopts streamlined machined dovetail rails paired with smooth fine-thread screw drive, built on a standard 40×40 mm square mounting platform optimized for weight reduction. Weighing merely 0.17 kg, this compact aluminum unit cuts down redundant structural material to hit an ultra-light weight threshold within the ±10 mm travel 40-series lineup, making it a prime solution for battery-powered portable equipment and miniature internal assemblies where every gram of total payload must be strictly limited. It delivers consistent ±10 mm linear adjustment travel, supports vertical modes, and can be stacked neatly into miniature XYZ multi-axis positioning groups without adding excessive bulk to compact equipment housings.

Fitted with a crisp laser-etched 0.1 mm vernier scale for quick, unassisted position reading, the stage maintains 50 μm table parallelism and 30 μm drive parallelism across its full 20 mm total stroke, sustaining steady flatness for low-load repeated adjustment cycles. It is widely deployed in student basic optical experiment stations, miniature portable detection devices, small sensor calibration fixtures, hobby optical prototype rigs and lightweight handheld testing equipment. Its ultra-minimal weight and entry-level price point create unique value for small-scale R&D teams, university teaching labs and portable device developers, where heavy load bearing capacity is unnecessary and miniaturization & cost control stand as core design priorities.

Manufactured from lightweight aluminum alloy with matte black anodized surface finishing, the coating delivers mild scratch resistance and suppresses stray light reflection to avoid interference in optical alignment environments. With a 1.0 kgf maximum load rating, it steadily holds micro camera modules, tiny lens holders, miniature sensing circuit boards and thin lightweight custom plastic fixtures without surface deflection or positional drift. For teaching laboratory procurement staff, portable instrument designers and small prototype studios searching for the lightest entry-level manual adjustment slide to fit tiny internal equipment spaces, the JD3-44S supplies complete basic positioning functionality while slashing overall assembly weight and hardware procurement costs.

As a Sino-Korean joint precision component manufacturer based in Dongguan’s core precision machining industrial belt, we optimize the JD3-44S production flow to reduce manufacturing costs while retaining mandatory geometric accuracy testing procedures. Every finished unit passes full-stroke travel verification and flatness calibration before factory shipment to guarantee stable baseline positioning performance. We offer flexible order support covering bulk education institution procurement and small-batch prototype trial orders, plus simple custom modifications such as simplified mounting hole layouts tailored for mini embedded device assembly. We sincerely invite school laboratory managers, portable equipment manufacturers and independent R&D studios to contact our technical team for volume pricing and customized mini positioning solution consultations.
