Airtac LSH Linear Guide Rail LSH15HN2X1240S20BH-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 protocol:
Requires mounting surface flatness ≤0.02mm/m. Use M4×8mm flat head screws
(torque 1.6-2.0N·m). Apply lithium soap-based grease (NLGI #2) during assembly.
Avoid magnetic particle detection post-installation due to oxide coating.
