Airtac LSH Linear Guide Rail LSH20HN2X1240S20AH-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.
