Ultra-compact linear motion solution featuring high rigidity and smooth operation. The chrome-plated rail and precision-ground raceways ensure minimal friction (μ<0.003) while maintaining dust resistance. Optimized for space-constrained applications requiring micron-level positioning stability. Compatible with stepper/servo motor systems.
- Medical imaging equipment (CT/PET scanner stages)
- Laboratory automation: Sample handling & PCR machines
- Semiconductor wafer inspection systems
- High-speed 3D printing extruder assemblies
- Surgical robot articulation joints
Installation note:
Use torque-controlled tightening (0.6-0.8Nm for M3 screws) and align rail mounting surface flatness within 0.01mm/m. Avoid side-loading during assembly - recommend using alignment jigs.
