C&K JCZ-25 manual Mini vertical stage Z Axis

Miniature Manual Stage (25mm Ultra-Compact Crossed-Roller Model)

The JCZ-25 is an ultra-compact manual linear stage engineered for space-critical applications, integrating precision crossed-roller bearings with a fine vernier adjustment system on a diminutive 25×25 mm footprint. Weighing a mere 0.06 kg, this featherweight aluminum stage adds negligible mass to compact assemblies and micro-instrumentation, making it ideal for miniaturized optical setups and portable testing devices where every gram matters. Despite its small stature, it provides a respectable ±3.25 mm of linear travel and supports both horizontal and vertical mounting, allowing flexible deployment in single-axis or stacked multi-axis micro-positioning configurations.

Boasting a 10 μm resolution, a 50 μm surface parallelism tolerance and a 20 μm driving parallelism specification — the tightest geometric tolerances in this product family — the JCZ-25 delivers exceptional positional accuracy relative to its size. It is extensively used in fiber optic alignment, micro-optics positioning, miniature camera calibration, micro-fluidic systems and compact laboratory test fixtures. Its tiny form factor enables placement inside confined instrument housings, vacuum chambers and densely packed optical breadboards where larger stages simply cannot fit, bringing reliable micron-level adjustment to even the most spatially constrained engineering projects.

This miniature stage punches well above its weight in terms of performance value. The black anodized finish provides corrosion protection and reduces light scatter in optical systems, while the 0.5 kgf load capacity is more than sufficient for typical micro-optical and sensor mounting applications. For designers working on miniaturized equipment, handheld devices or compact inspection systems who require precision manual positioning without sacrificing valuable real estate, the JCZ-25 offers an unmatched combination of small size, light weight and dependable accuracy.

Headquartered in Dongguan, Guangdong — the core of China's precision manufacturing ecosystem — our Sino-Korean joint venture production facility draws upon a mature local supply chain, refined micro-machining expertise and stringent quality control procedures. Each JCZ-25 unit is individually inspected for travel smoothness, dimensional precision and parallelism compliance before leaving the factory, ensuring uniform high quality across production batches. With strong manufacturing scalability and dedicated technical support for custom miniature solutions, we warmly welcome customers to visit our facility and explore partnership possibilities.
