Airtac LSH Linear Guide Rail LSH25BK-F1N-P-D-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.

High-precision linear motion system featuring optimized ball contact angles (45°×45°) for balanced radial and lateral load capacity. The dual-sealed design combines non-contact labyrinth seals with wiper scrapers, effectively blocking contaminants while maintaining smooth motion. Preloaded balls achieve C3-grade clearance control for minimal backlash in positioning applications.

- Semiconductor wafer handling robots
- Precision optical inspection equipment
- High-speed packaging line actuators
- Medical imaging device positioning stages
Installation Guidelines:
Use M6×12mm SHCS bolts torqued to 8.8N·m in crisscross pattern.
Rail straightness tolerance: ≤0.05mm/m. Lubricate through 4 grease
nipples (M6×1) every 100km travel using ISO VG32 equivalent grease.
