Airtac LSH Linear Guide Rail LSH30BK-HN-P-D-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-controlled wrench (recommended 5.5-6.5N·m for M6 bolts) and
align rail mounting surfaces within 0.02mm/m straightness. Apply Loctite 243
on threads and allow 24h curing before full load operation.
