Airtac LSH Linear Guide Rail LSH20BK-F2L-P-D-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.

- Semiconductor wafer handling robots
- High-speed packaging machine linear actuators
- Medical CT scanner sliding mechanisms
Installation note:
Use torque wrench (4.5-5.5N·m for M6 screws) with sequential tightening pattern.
Align rails within 0.02mm/m straightness tolerance using master reference surface.
Avoid cantilevered loads exceeding 15% of C0 capacity.
