Airtac LSH Linear Guide Rail LSH25RLX1780-S20-H-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.

Heavy-duty linear guide optimized for high moment load resistance, featuring enhanced rigidity through optimized ball groove geometry. The RX-series design incorporates 45° contact angles for balanced radial and reverse radial load capacity. Includes corrosion-resistant treatment for industrial environments.
- CNC gantry mill Z-axis vertical movement
- Automated warehouse shuttle carriages
- Semiconductor wafer handling robots
- High-speed packaging line conveyors
- Precision optical inspection stages
Installation notes:1. Maintain mounting surface flatness ≤0.02mm/m
2. Use torque wrench (4.9-5.9N·m for M5 screws)
3. Apply lithium soap grease (ISO VG32-68) every 100km travel
4. Avoid side hammering - use alignment jigs during assembly
