Airtac LSH Linear Guide Rail LSH20BK-F2N-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:
Requires mounting surface flatness ≤0.02mm/m. Use torque-controlled tightening
(M6 screws: 4.5-5.5N·m). For full load capacity, install parallel rails with
≤0.02mm alignment error. Clean rail surfaces with alcohol before assembly.
