Airtac LSH Linear Guide Rail LSH20HL2X780S20AN-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 protocol:
Use torque-controlled tightening (4.4-5.6N·m for M6 screws) with sequential
fastening pattern. Maintain 0.02mm/m straightness tolerance during rail
alignment. Apply ISO VG32-68 grease quarterly in high-cycle applications.
