Airtac LSH Linear Guide Rail LSH25HN2X3000S20AN-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:
Requires surface flatness ≤0.01mm/m and parallelism ≤0.02mm between rails.
Use torque-controlled tightening (M6 screws at 4.5-5.0N·m) in cross pattern sequence.
Thermal expansion compensation required for installations exceeding 1500mm.
