Precise, repeatable positioning begins with the right supplier. The LDTDP-JG Series comes from a motorized xy stage manufacturer and precision xy stage supplier that integrates a cross ball guide, precision-ground screw drive, and dovetail guide rail into one high-precision translation stage. It moves a payload to exact positions in two axes automatically, replacing manual knobs and guesswork with programmable, repeatable motion. Use this guide to turn your application into a complete specification, then use the same checklist to compare responses from every supplier you shortlist.
Every application stresses a different part of the specification. Pick the scenario closest to your work and you will know which travel, load, resolution, and repeatability numbers deserve the most attention.
For sample scanning, cell imaging, and experiment automation where the specimen moves beneath a fixed objective.
For beam steering, optics alignment, and photonics builds that need stable, backlash-free positioning under load.
For inspection, assembly check, and test routines that run unattended and need a consistent home position.
For general lab positioning, process automation, and extended-axis scanning where platform footprint matters as much as travel.
Travel range defines the X/Y motion envelope. Platform size defines the mounting face available for your fixture, sample, or optic. Load capacity defines how much mass the stage can move reliably. These three numbers must be selected together—not independently.
Best when the work piece is small and the required motion envelope is under 50 mm in each axis. Typical tasks: microscope scanning, inspection of small components, and precision adjustment steps.
Best when you need a generous 100 mm of travel in both axes on a roomy 300 × 300 mm platform. Typical tasks: automated testing, multi-sample inspection, and laser alignment.
Best when samples, panels, or assemblies must be scanned across a long envelope in both axes. Typical tasks: large-format measurement, multi-station automation, and heavy optical payloads.
A motorized XY stage is only as trustworthy as its mechanical skeleton. Guide type controls how smoothly and stably the platform moves; drive and nut design control how precisely commanded motion transfers into real position.
The stage uses a high-precision motorized integrated translation stage with a cross ball guide mechanism. Rolling contact helps the carriage move smoothly while maintaining lateral stiffness for consistent linear motion.
A dovetail guide rail is the load-bearing backbone of the platform. The product specification pairs it with a crossed-roller and V-shaped guide arrangement that feels comfortable to move and accepts the large payloads this series is rated to carry.
With a small lead and precision-ground thread, the screw drive converts motor rotation into fine linear movement. The same electronic subdivision setting produces a higher effective resolution because the mechanical lead itself is smaller.
The back-in-the-air nut structure actively reduces the gap between the screw and nut. Less pair gap means less lost motion on direction reversal, which directly improves repeatability and smoothness during bidirectional positioning.
Equipped with zero position and limit switches at both ends, each axis can establish a reliable datum and prevent over-travel. That matters for automated routines that return to the same start point cycle after cycle.
Three travel classes share the same mechanical philosophy—cross ball guide, precision-ground screw drive, and dovetail guide rail—but differ in platform size, motor size, and load capacity. Use this matrix to choose your base configuration.

If your process moves in both directions repeatedly, give extra weight to the nut/screw gap design and the published repeating accuracy. If your payload is heavy or the platform is large, verify that the selected guide system can carry the combined fixture + sample mass without straining the drive.

the ldtdp-50-jg-2 provides 50 mm x/y travel on a 150 × 150 mm platform; the ldtdp-100-jg-2 provides 100 mm x/y travel on a 300 × 300 mm platform; and the ldtdp-170-jg-2 provides 170 mm x/y travel on a 300 × 300 mm platform. short-travel models suit microscopes and fine scanning; long-travel models suit larger measurement envelopes and heavier payloads.
resolution reaches 0.625 μm on the ldtdp-50-jg-2 and 2.5 μm on the 100 mm and 170 mm models. repeating accuracy is less than 10 μm across the series. the small-lead, precision-ground screw drive is what allows the finer resolution class to reach 0.625 μm with the same electronic subdivision setting.
load capacity is 10 kg for the ldtdp-50-jg-2, 50 kg for the ldtdp-100-jg-2, and 60 kg for the ldtdp-170-jg-2. for any automate-testing build, confirm that the combined fixture, sample, cabling, and moving mass stays below the rated load and that the bench surface is rigid enough at full travel.
backlash appears when the screw and nut have clearance, causing lost motion when the axis reverses direction. the back-in-the-air nut structure reduces that screw-pair gap, which improves repeatability and smoothness. zero-position and limit switches give the controller a reliable datum and protect the mechanism from over-travel, which is essential for unattended measurement and testing.
