Airtac LSH Linear Guide Rail LSH15BK-HN-H-B-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 guidelines:
Use torque-controlled tightening (0.7-0.9Nm for M4 screws) with sequential diagonal fastening pattern.
Maintain rail straightness within 0.02mm/m using precision level during installation.
Apply lithium soap-based grease (ISO VG 32-68) during commissioning.
