Application Selection Example
Medical Diagnostic Micro-Axis
A compact diagnostic axis requires stable motion within a limited installation envelope.
- Repeatability target: ≤ ±1.5 μm
- Operating speed: 200 mm/s
- Available assembly width: ≤ 20 mm
- Life target: ≥ 20 million cycles
- Environment: High humidity or periodic cleaning
Preliminary direction: A standard-width TGN miniature guide is the first configuration to evaluate. Final rail size, C or H block, accuracy, preload and material must be confirmed from the actual load, stroke and installation conditions.
Still required: Stroke, acceleration, payload offset, mounting orientation, block quantity and cleaning medium.
Application Selection Example
Compact 3D Printer X/Y Stage
A compact X/Y stage requires controlled motion, low moving mass and sufficient
moment support during long operating cycles.
- System resolution target: 0.5 μm
- Repeatability target: ≤ ±1 μm
- Stroke: 12–25 mm
- Operating time: Up to 20 hours per day
- Main concern: Offset load and pitch/yaw stability
Preliminary direction: Compare a standard-width TGN arrangement with a wider TGW configuration. The final guide type, block length, accuracy and ZF, Z0 or Z1 setting depend on the available space, moving load, block spacing and moment calculation.
Still required: Payload, acceleration, load offset, mounting orientation, rail arrangement and required service life.

Compact size for space-limited designs
IMTEK miniature linear guides feature ultra-small rail profiles designed for tight installations where every millimeter counts. Their compact footprint supports dense component layouts without sacrificing stability or motion quality, making them ideal for portable devices, compact automation systems, and space-constrained robotic mechanisms.
Micron-level repeatability for precision tasks
Engineered for high-precision applications, IMTEK miniature linear rails deliver smooth, repeatable motion with micron-level accuracy. This performance is essential in medical diagnostic devices, semiconductor inspection equipment, and precision optical instruments where even minor deviations can affect measurement results or production quality.
Low friction, smooth motion design
Using optimized ball-recirculation paths, IMTEK miniature linear guides maintain low friction, quiet running and consistent smooth travel. It enhances responsiveness in high-speed automation and reduces vibration in sensitive equipment such as imaging systems, laboratory tools, and micro-positioning stages.
High stiffness and load capacity for small profiles
Despite their small size, these miniature linear guides provide strong rigidity and reliable load support through precision-ground rails and tightly controlled internal clearance. They ensure stable performance in compact robots, micro-dispensing units, and lightweight industrial assemblies requiring dependable structural support.
Stainless or carbon steel options for machines
IMTEK offers miniature linear guides in stainless steel or carbon steel to match different operating environments. Stainless steel provides corrosion resistance for cleanrooms and medical devices, while carbon steel offers high strength and durability for cost-efficient industrial and automation applications.
Long service life with proper lubrication
With correct lubrication, IMTEK miniature linear rails achieve long operating life, reduced wear, and stable accuracy across extended duty cycles. Their optimized ball-contact surfaces retain smooth motion under continuous use, supporting reliable uptime in automation equipment, test instruments, and precision lab systems.
FAQ
TGN guides use a standard narrow profile for compact installations. TGW guides have a wider block and mounting base, providing better stability and moment-load support when more installation space is available.
Yes, but moment capacity depends on rail size, block length, block quantity, guide spacing, and load offset. Wider blocks or two-block layouts can improve stability when the load is not centered above the guide.
IMTEK can evaluate replacement options based on the existing guide size, rail dimensions, mounting-hole spacing, block length, preload, accuracy grade, load rating, and application conditions.
Since products with similar nominal sizes may still differ in dimensions and performance, final interchangeability should be confirmed through drawings and specification comparison before ordering.
Please provide the required rail size, stroke, load, mounting direction, block quantity, available installation space, accuracy, preload, speed, and working environment. An existing model number or machine drawing can also help IMTEK recommend a suitable miniature guide.
IMTEK can support custom rail lengths, block quantities, preload levels, material options, and surface treatments according to the application. Please provide the required size, stroke, load, mounting direction, working environment, and any equivalent model number for evaluation.
