Airtac LSH Linear Guide Rail LSH20RLX180-S20-N-E
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 tip:
Use 0.02/300mm precision level during mounting. Tighten bolts in
diagonal sequence at 50% torque increments. Maintain 0.005-0.015mm
preload adjustment for optimal stiffness.
