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

Mounting protocol:
Requires surface flatness ≤0.01mm/m and parallelism ≤0.02mm between rails.
Use 4.9-6.9Nm torque for M6 mounting screws with Loctite 243 threadlocker.
Relubricate every 500km travel distance using ISO VG32~68 grease.
