Airtac LSH Linear Guide Rail LSH20HN1X400S20AH-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.

Installation note:
Requires precise mounting surface flatness (≤0.02mm/m) and parallelism (≤0.03mm between rails).
Use M6×10mm screws torqued to 4.5-5.0N·m with Loctite 243. Perform initial lubrication with ISO VG32
grease in all lubrication ports before operation.
