Airtac LSH Linear Guide Rail LSH20HN1X400S20AN-M6
2. High Rigidity Four-Directional Equal Load Design: Incorporates 4-row ball circuits with 45° contact angle configuration, achieving optimal two-point contact for bidirectional radial/lateral load capacity. Optional preload application enhances system rigidity when required.
3. Interchangeability: Stringent manufacturing precision ensures dimensional consistency within stable tolerances. Integrated retainer design prevents ball dislodgement, enabling between and matching guideways while preserving operational smoothness, preload integrity, and motion accuracy.

Industrial-grade linear motion system featuring hardened steel construction with chromium oxide coating for corrosion resistance. The HN-series preload ensures minimal deflection under heavy moment loads, while the optimized ball recirculation design achieves smooth movement (friction coefficient <0.003). Includes four carriages for enhanced load distribution and anti-vibration stability.
- CNC gantry mill Z-axis reinforcement
- Automated pallet transfer systems
- High-precision optical inspection equipment
- Robotic welding arm base guides
- Semiconductor wafer handling robots
Installation notes:
Requires mounting surface flatness ≤0.02mm/m. Use torque wrench at 8.8Nm for M6 fasteners.
Apply ISO VG32-68 grease through zerk fittings every 500km travel. Avoid parallel mounting
tolerance exceeding ±0.05mm between rails.
