Airtac LSH Linear Guide Rail LSH20HN1X555S7.5CN-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 solution featuring optimized ball contact angles (45°×45°) for simultaneous radial and lateral load handling. The S7.5 suffix indicates special 7.5mm ball diameter configuration for enhanced stiffness in vertical applications. Includes hardened raceways (HRC58-62) and pre-loaded ball bearings for minimal deflection during high-speed operation (up to 5m/s).
- CNC gantry mill Z-axis vertical guidance systems
- Automated warehouse stacker cranes
- Lithium battery roll press machinery
- Semiconductor wafer handling robots
- High-precision optical inspection equipment
Installation note:
Requires mounting surface flatness ≤0.02mm/m and use of torque wrench (recommended 5.4N·m for M6 screws).
Apply lithium soap-based grease to all raceways before initial operation. Avoid mixing carriages between rails.
