Airtac LSH Linear Guide Rail LSH20BK-F1N-N-B-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.

Installation recommendation:
Maintain 0.02mm/m straightness tolerance during rail mounting.
Use torque wrench (1.2-1.5N·m for M6 screws) with Loctite 243 threadlocker.
Avoid thermal expansion by keeping ambient temperature variation within ±5℃ during installation.
