Airtac LSH Linear Guide Rail LSH20HN2X1180S50BN-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.

The LSH20HN2 series features optimized stress distribution through symmetrical roller arrangement, achieving 30% higher moment resistance than standard models. Hardened raceways (HRC58-62) ensure extended service life in high-cycle applications. Includes pre-drilled mounting holes with counterbores for flush screw installation.
- High-speed CNC gantry systems requiring vibration damping
- Automated warehouse stacker cranes
- Semiconductor wafer handling robots
- Precision injection molding machine ejectors
- Laser cutting axis systems
Installation protocol:
Use 0.02/300mm straightedge during mounting. Tighten screws in diagonal
sequence at 50% → 80% → 100% torque (5.3N·m max). Perform alignment
verification with 0.015mm/m tolerance.
