Airtac LSH Linear Guide Rail LSH20BK-HL-P-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.

- Automated warehouse shuttle systems
- High-precision 3D printer X/Y axes
- Semiconductor wafer handling robots
- Packaging machine vertical lifts
Installation protocol:
Requires surface flatness ≤0.01mm/m and parallelism ≤0.02mm/m between rails.
Use torque wrench (2.5-3.0N·m for M6 screws) in cross-tightening sequence.
Avoid exposing to cutting fluids without optional stainless steel version.
Load note:
Maximum allowable moment loads -
MR=98N·m, MP=98N·m, MY=196N·m.
Reduce speed by 30% when operating above 60℃.
