Airtac LSH Linear Guide Rail LSH25F1N4X880S20AN-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 mounting surface flatness ≤0.02mm/m. Use torque-controlled tightening
(M6 bolts at 8.8Nm ±10%) in cross pattern. Perform alignment with 0.02mm/m
parallelism tolerance between rails. Apply lithium complex grease monthly
through Zerk fittings under heavy use.
