Airtac LSH Linear Guide Rail LSH20BK-HN-N-B-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.

Professional-grade linear motion solution featuring optimized load distribution and contamination resistance. The HN preload ensures minimal deflection under moment loads, while the triple sealing system extends service life in harsh environments. Requires periodic lubrication with ISO VG32-68 grease.
- High-speed CNC gantry systems
- Semiconductor wafer handling robots
- Precision optical inspection equipment
- Automated packaging lines with side loads
- 3D printing beds requiring thermal stability
Installation criticals:
Mount on machined reference surface (flatness ≤0.01mm/100mm). Use 0.02mm feeler gauge
for parallel alignment. Thermal expansion requires 0.5mm gap per meter between rail ends.
