Airtac LSH Linear Guide Rail LSH20HN2X1840S20AN-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.

Heavy-duty linear motion system featuring hardened steel construction with chrome-plated surfaces for corrosion resistance. The HN-type carriage integrates dust-resistant seals (AN suffix) with 90% contact grease preload, optimized for high moment load applications. Requires periodic relubrication every 1,000km travel or 6 months.
- CNC gantry systems requiring multi-axis synchronization
- Automated warehouse stacker cranes
- High-precision optical inspection equipment
- Heavy-load material handling robots
- Semiconductor wafer transfer mechanisms
Mounting protocol:
Use torque-controlled tightening (M6 bolts @ 4.5-5.5Nm) with reference edge alignment.
Thermal expansion compensation required for installations exceeding 1500mm - allow 0.1mm gap per meter at 20℃ temperature variance.
