Description
The LGC Series Cross-Rolled Linear Guide represents a non-recirculating precision motion system characterized by exceptional rigidity and accuracy. This advanced configuration utilizes precisely arranged cross-roller bearings as rolling elements, effectively minimizing friction resistance during operation. The robust rail structure ensures superior load-bearing capacity, making it ideal for heavy-duty applications. Engineered for high-precision requirements, this solution is extensively implemented in precision machinery and measurement equipment, including critical components of PCB drilling machines, optical test systems, X-ray apparatus, and precision optical workstations.
Category: Linear Guides , Brand: AirTAC , Series: LGC
Installation note:
Maintain 0.02mm/m flatness on mounting surfaces. Use torque wrench (4.9N·m for M6 screws)
with sequential tightening pattern. Avoid thermal expansion by matching rail/material CTE.
