Airtac LSH Linear Guide Rail LSH20HN4X2485S42.5AN-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-controlled tightening (2.5-3.0Nm for M6 screws) in cross pattern sequence.
Align within 0.05mm/m using precision level. Apply corrosion inhibitor if used in
high-humidity environments (>80% RH).
- Relubricate every 500km travel or 6 months
- Inspect seals quarterly in dusty environments
- Check preload annually using vibration analysis
