- Semiconductor wafer handling robots
- High-speed PCB component placement systems
- Desktop CNC engraving machines
- Laboratory automation Z-axis stages
Installation tip:
Use 4.2Nm torque for M3 mounting screws. For maximum accuracy,
pre-load the rail against the reference surface using 0.02mm
shims during alignment. Lubricate with ISO VG15-grade grease
before initial operation.
