Airtac LSH Linear Guide Rail LSH20BK-F2N-H-E-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 system featuring optimized ball circuit design for smooth operation under heavy loads. The H-type sealing structure combines stainless steel scrapers and non-contact labyrinth seals, achieving 85% longer contaminant resistance than basic models. Includes pre-drilled mounting holes with M6 threads for simplified installation.
- CNC router Z-axis precision guidance
- Automated pallet shuttle systems
- Semiconductor wafer handling robots
- High-speed packaging machinery
- 3D printing gantry systems
Installation note:
Use torque-controlled tightening (recommended 5.5-6.5N·m for M6 screws)
and align rails within 0.05mm/m straightness tolerance. Apply lithium soap-based
grease (ISO VG32-68) through all lubrication ports during commissioning.
