Airtac LSH Linear Guide Rail LSH20BK-F1N-H-C-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:
Use torque wrench (recommended 4.5-5.5N·m for M6 bolts) with staggered tightening sequence.
Clean rail with #20 spindle oil before installation. Avoid hammer impacts during mounting.
Maintenance:
Relubricate every 1,000km travel (Use ISO VG32~68 grease).
Check preload torque every 6 months in high-humidity environments.
