Airtac LSH Linear Guide Rail LSH25BK-F2N-H-C-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 tip:
Use 0.02mm/m precision level during mounting. For maximum accuracy,
pre-load the rail against the reference surface using torque-controlled
tightening sequence (recommended torque: 5.4N·m for M6 screws).
