Airtac LSH Linear Guide Rail LSH25HN1X820S20BN-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.

Industrial-grade linear motion solution featuring hardened steel construction (HRC58-62) with chrome-plated surfaces for corrosion resistance. The HN-series blocks incorporate preload adjustment capability (0~-0.03mm) through selective ball sizing, enabling customization for either high rigidity or smooth motion requirements. Designed for high-speed applications up to 5m/s with integrated oil lubrication grooves.
- CNC gantry mill Z-axis guidance systems
- Automated pallet shuttle mechanisms
- High-precision optical inspection equipment
- Industrial robot 7th-axis sliding bases
- Semiconductor wafer handling robots
Installation note:
Requires mounting surface flatness ≤0.02mm/m. Use torque-controlled wrench
(M6 bolts: 4.5-5.5N·m) with sequential tightening pattern. Apply lithium soap-based
grease (NLGI #2) through lubrication ports every 100km of travel.
