Airtac LSH Linear Guide Rail LSH20HN2X650S25AH-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.

High-rigidity linear motion system featuring optimized ball circuit design for smooth operation under heavy loads. The HN-type blocks incorporate 4-row angular contact ball bearings with 45° contact angles, providing exceptional moment resistance and vibration damping. Includes factory-preloaded blocks with alignment marks for simplified installation.
- CNC router Z-axis guidance systems
- Automated pallet shuttle mechanisms
- Precision optical stage positioning
- Industrial 3D printer gantry systems
- Semiconductor wafer handling robots
Installation protocol:
Use grade 12.9 mounting screws torqued to 5N·m in cross pattern sequence.
Align using master rail technique - secure primary rail first, then match
secondary rail using gauge blocks. Relubricate every 500km travel with
ISO VG32~68 grease.
