Airtac LSH Linear Guide Rail LSH20HN2X2500S20BN-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 combining high rigidity and contamination resistance. Features optimized ball recirculation geometry for smooth operation in long-stroke applications. The HN-series rails utilize staggered mounting holes (alternating 6.6mm and 5.5mm hole depths) for improved structural stability.
- CNC gantry systems requiring 2.5m+ travel
- Automated warehouse retrieval systems
- PCB drilling/punching machines
- Glass cutting equipment with heavy crossbeams
- Automotive production line transfer units
Installation protocol:
Requires torque-controlled tightening sequence (M6 bolts @ 4.5-5.0Nm) using
diagonal pattern. Base surface flatness must be ≤0.05mm/m. Thermal expansion
compensation required for installations exceeding 1.5m.
