- Semiconductor wafer handling robots
- Optical measurement equipment stages
- Lithography machine precision positioning
- Medical CT scanner gantry movement
Installation criticals:
Requires mounting surface flatness ≤0.01mm/m and parallelism ≤0.02mm between rails.
Use 4.9-6.9N·m torque for M6 bolts with Loctite 243 threadlocker. Thermal expansion
compensation required for installations exceeding 1.5m length.
