Airtac LSH Linear Guide Rail LSH25HN1X400S20AN-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 solution featuring optimized ball circuit design for smooth operation under heavy moment loads. The HN-series preload ensures minimal deflection during high-precision positioning. Hardened raceways (HRC 58-62) provide exceptional wear resistance, while the integrated oil grooves enable continuous lubrication.
- CNC gantry milling machine Z-axis guidance
- Automated pallet shuttle systems in warehouses
- High-speed pick-and-place robotic arms
- Precision optical inspection equipment
- Semiconductor wafer handling robots
Installation note:
Use torque wrench (5.4-6.6N·m for M6 bolts) with sequential tightening pattern.
Align using master rail technique - secure base carriage first before locking adjacent units.
Apply lithium soap-based grease (ISO VG 32-68) through all lubrication ports during commissioning.
