Installation recommendation:
Apply 0.02-0.05mm preload adjustment during mounting using indicator gauges.
For maximum accuracy, maintain rail straightness within 0.1mm/m using precision
leveling tools. Thermal expansion compensation required for installations
exceeding 300mm in environments with ±15℃ fluctuations.
