Airtac LSH Linear Guide Rail LSH25BK-F2L-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.

Precision ground linear motion system featuring corrosion-resistant treatment and multi-layer sealing for harsh environments. The BK preload provides optimal rigidity-vibration damping balance for medium-duty applications. Modular design allows daisy-chaining multiple carriages on extended rails.
- CNC router Z-axis positioning systems
- Automated optical inspection (AOI) equipment
- High-speed pick-and-place robotic arms
- Semiconductor wafer handling robots
- 3D printer gantry systems
Installation tip:
Use torque-controlled mounting (M6 screws @ 4.4-5.4 N·m) with sequential
tightening pattern. Maintain 0.02mm/m straightness tolerance during rail
alignment. Apply initial lubrication purge after 50km break-in travel.
