Airtac LSH Linear Guide Rail LSH15HN1X778S38BN-M4
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-controlled tightening (M4 screws at 1.2-1.5N·m) in cross-sequence pattern.
Maintain ≤0.02mm/m straightness during rail mounting. Thermal expansion compensation required
for installations exceeding 1.5m length.
