Premium cross roller guide featuring zero-backlash operation and micron-level repeatability. The LGC2A series utilizes staggered 90° roller arrays to achieve bidirectional load capacity and enhanced moment resistance. Hardened raceways with mirror polishing (Ra≤0.1μm) ensure smooth motion characteristics even under high moment loads. Includes pre-drilled mounting holes with ±0.01mm positional accuracy.
- High-speed CNC rotary tables (4th/5th axis)
- Semiconductor wafer handling robots
- Precision optical alignment stages
- Coordinate measuring machine (CMM) Z-axis
- Lithography equipment positioning systems
Installation note:
Requires mounting surface flatness ≤0.01mm/m. Use torque wrench (specified 2.5Nm for M5 screws)
with cross-tightening sequence. Perform initial lubrication purge - run 50 full strokes at 10%
max load before full operation.
