- Desktop CNC router Z-axis guidance
- Semiconductor wafer handling robots
- Medical pipetting arm mechanisms
- High-speed PCB drilling machines
Mounting guidance:
Requires surface flatness ≤0.02mm/m and use of torque-controlled tightening
(1.2N·m max for M3 screws). Avoid lateral impact during installation -
use alignment pins for multi-rail systems.
