Lightweight Dovetail Stage Precision Manual Stage (JD4-44S Screw type Model)

Built with lightweight structural optimization paired with Screw adjust, the JD4-44S manual positioning stage fine adjustment with XYZ 3 Axis, fitted on a universal 40×40 mm square mounting platform compatible with mainstream optical benches and lab fixture standards. Weighing only 0.47 kg, smooth moving, making it a top pick for lightweight optoelectronic equipment and portable optical test rigs that demand both silky rolling motion and reduced overall assembly mass. It delivers ±10 mm of consistent linear travel, supports multi-angle mounting including horizontal, vertical and tilted setups, and can be stacked compactly to build lightweight XYZ multi-axis positioning groups without introducing excessive inertia that impacts delicate fine-tuning operations.

Designed with a clear etched 0.1 mm vernier scale for intuitive position readout without auxiliary measuring tools, the stage holds 120 μm table parallelism and 30 μm drive parallelism across its full 20 mm total stroke, maintaining uniform low-resistance rolling motion through tens of thousands of repeated adjustment cycles, free of the stick-slip jitter that plagues traditional dovetail sliding guide slides. It is widely deployed in portable fiber alignment equipment, compact microscopic calibration platforms, university advanced optics research labs, miniature imaging module testing stations and low-load optoelectronic prototype assembly lines. Its core advantage of lightweight rolling-guide smoothness fills the market gap between heavy standard crossed-roller stages and low-friction dovetail slides, catering to researchers and technicians requiring sensitive fine adjustment while keeping total rig weight in check.

Crafted from precision-machined aluminum alloy with matte black hard anodized surface treatment, the finished surface delivers durable abrasion resistance and suppresses stray light reflection to avoid optical signal interference during alignment testing. With a 1.0 kgf rated load capacity, it stably holds miniature fiber holders, compact lens assemblies, micro image sensors and lightweight precision custom jigs without disrupting uniform rolling smoothness. For optical R&D engineers, portable inspection equipment designers and university lab procurement teams seeking a compact rolling-guide manual stage that balances friction-free fine tuning and lightweight build, the JD4-44S provides a flexible, space-efficient alternative to crossed-roller positioning units.

As a Sino-Korean joint precision component manufacturer rooted in Dongguan’s mature precision machining industrial cluster, every JD4-44S unit undergoes dedicated smoothness testing and full-stroke geometric tolerance validation before factory shipment to guarantee consistent low-inertia motion performance. We support small lab trial batches and mass production bulk orders, alongside targeted custom modifications including mini locking knobs and simplified mounting hole layouts for portable device integration. We sincerely welcome optical research institutions, optoelectronics equipment manufacturers and laboratory hardware distributors to reach out to our technical team for volume pricing and customized lightweight precision positioning solution consultations.
