- Medical imaging equipment sliding mechanisms
- Semiconductor wafer handling robots
- Optical lens adjustment assemblies
 Installation note: 
            Requires mounting surface flatness ≤0.02mm/m. Use torque-controlled tightening 
            (recommended 1.2-1.5N·m for M3 screws). Avoid particulate contamination during 
            assembly - clean with IPA before grease replenishment.
