Professional-grade crossed roller guide featuring orthogonal cylindrical rollers arranged in 90° V-shape pattern, delivering ±0.5 arc-minute rotational stiffness. The LGC4A120R11-H combines high moment load capacity (45 N·m static moment rating) with smooth motion characteristics (friction coefficient μ<0.003). Includes hardened raceways with mirror finish (Ra 0.2μm) and corrosion-resistant black oxide coating.
- High-precision rotary table bases for CNC indexers
- Z-axis stages in semiconductor wafer inspection systems
- Medical CT scanner gantry movement systems
- Optical alignment stages for photolithography equipment
- Robotic welding arm pivot mechanisms
Installation note:
Requires mounting surface flatness ≤0.01mm/m and parallelism ≤0.02mm between rails.
Use 4.8Nm torque for M8 mounting screws with Loctite 243. Lubricate with ISO VG32
grease through 4 zerk fittings (included) every 500km travel.
