Airtac LSH Linear Guide Rail LSH30HL1X690S25BH-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 note:
Use torque wrench (4.5-5.5N·m for M6 screws) and precision leveling gauge during mounting.
Maintain 0.02mm/m straightness tolerance across full length. Thermal expansion compensation required
for installations exceeding 500mm in environments with >5℃ temperature variation.
