Airtac LSH Linear Guide Rail LSH15HN2X218S19BH-M4
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.

A heavy-duty linear motion solution combining high rigidity with smooth operation. Features hardened raceways (HRC58+) for extended service life and preloaded ball bearings (0.02mm preload) to minimize deflection. The corrosion-resistant coating and multi-stage sealing system ensure reliable performance in harsh environments. Requires periodic lubrication with ISO VG15-32 grease.
- High-speed CNC tool changers
- Automated optical inspection (AOI) equipment
- Precision 3D printer gantry systems
- Semiconductor wafer handling robots
- Medical imaging device positioning stages
Installation note:
Use torque-controlled tightening (0.7-0.9Nm for M4 screws) and align rails
within 0.05mm/m straightness tolerance. Avoid thermal expansion by allowing
0.2mm clearance per meter at 20℃ ambient.
