High-rigidity cross roller guide system featuring 45° angular contact design for simultaneous radial and axial load handling. The LGC3A series combines high moment stiffness (≥1800 N·m/rad) with ultra-smooth motion (friction coefficient ≤0.005), making it ideal for precision multi-axis systems. Includes hardened steel rails with mirror-finished raceways (Ra 0.1μm).
- CNC rotary tables and indexers
- Semiconductor wafer handling robots
- Optical measurement equipment stages
- High-speed PCB drilling machines
- Medical imaging device positioning systems
Installation note:
Requires mounting surface flatness ≤0.01mm/m and parallelism ≤0.02mm between rails.
Use 4.8Nm torque for M6 mounting screws with Loctite 243 threadlocker. Relubricate every
1,000km travel using ISO VG32 equivalent grease.
