- High-speed pick-and-place mechanisms
- Medical analyzer slide systems
- Semiconductor wafer handling robots
- Precision optical stage adjustments
Installation note:
Ensure mounting surface flatness ≤0.02mm/100mm. Use torque-controlled tools (recommended 1.2-1.5N·m)
for carriage screws to prevent rail deformation. Allow 0.5mm thermal expansion margin per meter.
