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.
