Industrial-grade cross roller guide featuring 45° contact angle rollers for simultaneous radial and axial load capacity. The LGC3A275R40-H combines high moment resistance (40N·m static moment rating) with micron-level positioning repeatability (±5μm). Includes hardened raceways (HRC58-62) and optimized roller spacing for vibration damping.
- High-speed CNC rotary tables (4th/5th axis)
- Semiconductor wafer handling robots
- Precision optical alignment stages
- Medical CT scanner gantry systems
- Automated coordinate measuring machines (CMM)
Installation note:
Requires mounting surface flatness ≤0.01mm/100mm and parallelism ≤0.02mm.
Use torque wrench (2.5-3.0N·m for M5 screws) with Loctite 243 threadlocker.
Relubricate every 500km travel or 6 months.
