Ultra-precision crossed roller guide system featuring bi-directional load capacity and zero-backlash operation. The LGC3B series incorporates staggered roller orientation for simultaneous radial and axial load support, with hardened raceways achieving surface hardness HRC60±2. Includes pre-loaded adjustment mechanism (±0.01mm preload tuning).
- High-speed CNC rotary tables (4th/5th axis)
- Semiconductor wafer handling robots
- Precision optical alignment stages
- Medical CT scanner gantry systems
- Aerospace component test rigs
Installation protocol:
Mount on ground surface with flatness ≤0.01mm/100mm. Use 4.2Nm torque
for M5 fasteners. Run 50-cycle break-in motion before full operation.
Avoid lateral impact during handling - rollers are pre-aligned at factory.
