Airtac LSH Linear Guide Rail LSH25RLX220-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 note:
Requires torque-controlled tightening (4.5-5.2 N·m for M5 screws) with sequential
diagonal fastening pattern. Base surface flatness must be ≤0.02mm/m.
Lubricate with ISO VG15-32 grease before initial operation.
