Airtac LSH Linear Guide Rail LSH20HN4X3150S15CN-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.

- Automotive production line transfer systems
Installation note:
Requires surface flatness ≤0.02mm/m and mounting surface roughness Ra1.6.
Use torque-controlled wrench (M6 bolts: 4.5-5.5 N·m). Avoid thermal expansion
by allowing 0.5mm clearance at rail ends in environments >25℃.
