Airtac LSH Linear Guide Rail LSH25HN2X1120S20BH-M6-B
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 designed for industrial automation, featuring optimized ball circuit geometry that reduces vibration during high-speed operation (up to 5m/s). The HN-series construction provides 35% higher moment resistance than standard LSH models. Includes hardened raceways (HRC58-62) and corrosion-resistant seals for harsh environments.
- CNC gantry mill Z-axis drives
- Automated warehouse stacker cranes
- Lithium battery electrode coating machines
- Glass cutting equipment with vacuum chucks
- Semiconductor wafer handling robots
Installation protocol:
Requires precision mounting surface flatness ≤0.02mm/m. Use 8.8-grade mounting screws
torqued to 8.5N·m in cross-sequence pattern. Lubricate with ISO VG32-68 grease through
carriage lubrication ports before initial operation.
