Airtac LSH Linear Guide Rail LSH25HN1X760S20BN-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 criticals:
Use a precision level with 0.02/1000mm accuracy during installation. Tighten M6 screws to 5.5±0.5N·m
using a crisscross sequence. Maintain a clearance of 0.005-0.015mm between rail ends when joining multiple sections.
