Airtac LSH Linear Guide Rail LSH25F2N1X340S20BH-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 (≤45dB noise level). The chromium-plated rail surface provides corrosion resistance (72hr salt spray test passed), while the 4-row circular groove structure ensures balanced load distribution. Includes mounting datum surfaces for simplified alignment.
- CNC gantry mill Z-axis positioning systems
- Automated optical inspection (AOI) equipment stages
- High-speed 3D printer X/Y axis motion
- Semiconductor wafer handling robots
- Pharmaceutical packaging linear actuators
Installation note:
Clean rail surfaces with alcohol wipes before assembly.
Use 4.5-5.5Nm torque for M6 mounting screws.
Avoid exposing to grinding debris without protective covers.
For full-length rails >500mm, maintain 0.02mm/m flatness in mounting surface.
