Industrial-grade crossed roller guide featuring ultra-high rigidity through alternating orthogonal roller orientation. The LGC series employs full complement needle rollers without retainers for maximum load distribution, with hardened raceways achieving ≤1μm surface roughness. Requires 10-15μm filtration in contaminated environments.
- High-precision CNC rotary tables (4th/5th axis)
- Semiconductor wafer handling robots
- Optical measurement equipment Z-axis stages
- Medical CT scanner gantry systems
- 3D metal printing laser head carriers
Mounting guidance:
Achieve optimal performance by maintaining ≤0.01mm/m parallelism between rails.
Use 4.9-6.9 N·m torque for M6 mounting screws with Loctite 243 threadlocker.
Relubricate every 1,000km travel or 6 months.
