Airtac LSH Linear Guide Rail LSH25HN2X640S20AN-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.

High-rigidity linear motion system featuring optimized ball circuit design for smooth operation under heavy loads. The HN-series carriages incorporate enhanced preload adjustment (medium preload) and anti-creep mechanisms. Precision ground surfaces achieve running parallelism ≤0.005mm/300mm. Includes corrosion-resistant anodized aluminum end seals.
- CNC gantry milling machine Z-axis guidance
- Automated warehouse shuttle cart systems
- High-precision 3D printer frame structures
- Semiconductor wafer handling robots
- Industrial press feed mechanisms
Installation note:
Requires mounting surface flatness ≤0.02mm/m and use of torque wrench (M6 bolts: 4.5-5.5N·m).
Avoid maximum speed >2m/s without additional vibration damping. Relubrication interval: 500km travel or 6 months.
