Airtac LSH Linear Guide Rail LSH20HL1X1240S20AN-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-rigidity linear motion system with optimized ball circuit design for smooth operation under heavy loads. Features corrosion-resistant treatment and enhanced dust-proof structure. The staggered ball arrangement reduces vibration and noise during high-speed movement (up to 5m/s). Requires periodic lubrication with ISO VG32-68 grade grease.
- CNC gantry milling machine Z-axis guidance
- Automated warehouse stacker cranes
- Semiconductor wafer handling robots
- High-precision optical inspection equipment
- Automotive production line transfer systems
Installation note:
Maintain parallel alignment within 0.05mm/m during mounting. Use torque wrench
for M6 screws (recommended torque 4.5-5.5N·m). Avoid welding sparks near rails.
- End caps: LME20-L/R
- Rail supports: LMB20 (spacing ≤500mm)
- Lubrication: Use Airtac LG-2 grease cartridge
