Airtac LSH Linear Guide Rail LSH20BK-F2N-N-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.

Heavy-duty linear guide system featuring optimized ball groove geometry for smooth motion and vibration damping. The BK suffix indicates enhanced rigidity through widened carriage design. Includes corrosion-resistant M6 mounting inserts and comes pre-lubricated with lithium complex grease. Requires periodic relubrication every 1,000km travel.
- CNC router Z-axis precision positioning
- Automated pallet shuttle systems
- 3D printer gantry motion systems
- Semiconductor wafer handling robots
- Packaging machine vertical lift mechanisms
Installation note:
Use 4.9-6.9Nm torque for M6 mounting screws. Align rails within
0.05mm/m straightness tolerance using precision level. Avoid
particulate contamination during assembly.
