Airtac LSH Linear Guide Rail LSH25BK-F1N-N-E-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.

- Automated test equipment sliding stages
- Packaging machine material pushers
- 3D printer gantry systems
- Semiconductor wafer handling robots
Installation tip:
Achieve optimal performance by maintaining <0.05mm/m straightness during rail mounting.
Use M6×12 mounting screws (recommended torque: 4.5-5.5 N·m) with Loctite 243 threadlocker.
