Extra Long Travel Heavy Load Manual Stage (JD2-48S Wide Platform Dovetail Model)

Built for projects requiring broad adjustment range and robust load-bearing performance, the JD2-48S manual displacement slide integrates scraped dovetail guide rails and anti-backlash adjustment screw onto an expanded 40×80 mm wide mounting platform, breaking the travel limitation of standard 40mm-width single-axis stages. Weighing 0.44 kg with a widened base structure, the whole body delivers outstanding structural rigidity to resist bending deformation even under heavy payloads, eliminating position deviation during long-stroke adjustment. It supplies an ultra-wide ±25 mm linear moving range — far more adjustment space than regular 40-series compact stages, compatible with horizontal, vertical and side vertical installation modes, and can be matched with other single-axis slides to assemble multi-axis positioning systems for large-range calibration tasks.

Fitted with a clear 0.1 mm vernier scale for direct position reading without auxiliary measuring tools, this stage maintains 60 μm platform parallelism and 30 μm drive parallelism across its full 50 mm total stroke, sustaining stable flatness and consistent positioning repeatability after thousands of full-stroke reciprocating adjustments. It is widely adopted in optical component calibration, production line fixture alignment, laboratory large-scale prototype testing, multi-component sensor mounting stations and light assembly equipment. Its unique combination of wide platform, ultra-long travel and high load capacity makes it a top pick for test rig designers and process engineers who need to install multiple parts on one single stage while retaining ample moving space for alignment operations.

Constructed from solid aluminum alloy with uniform black hard anodized coating, the surface effectively blocks scratches, dust adhesion and weak solvent corrosion from daily workshop and lab use. Boasting a 3.7 kgf maximum load capacity, it easily supports stacked optical brackets, multi-sensor combined modules, medium-size custom holding fixtures and small industrial inspection jigs without surface tilt or structural distortion. For production technicians, optical experiment researchers and automation equipment integrators who need a cost-effective long-travel positioning solution capable of carrying multiple heavy components at once, the JD2-48S provides a reliable all-in-one adjustment platform that cuts down the need for stacked multiple small slides.

As a Sino-Korean joint precision component manufacturer located in Dongguan’s mature precision machining industrial zone, every JD2-48S unit undergoes full-stroke linearity testing and geometric flatness inspection before delivery to guarantee steady performance in long-cycle operation scenarios. We maintain flexible stock supply for laboratory small trial orders and factory mass procurement, and accept customized modifications including customized mounting hole layouts, reinforced locking knobs and limit travel stops. We sincerely welcome education institutions, automation equipment suppliers and R&D teams to get in touch for technical consultation, volume pricing and long-term cooperation negotiation.
