Airtac LSH Linear Guide Rail LSH25BK-HL-P-E-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.

Industrial-grade linear motion solution featuring hardened raceways (HRC58-62) and optimized ball circuit design. The HL-series enhances rigidity by 30% compared to standard models through reinforced block structure. Integrated sealing system combines metal scrapers for chip resistance and rubber seals for lubricant retention. Compatible with automatic lubrication systems.
- High-precision CNC machining centers (X/Y-axis)
- Automated optical inspection (AOI) equipment
- Semiconductor wafer handling robots
- Heavy-duty 3D printing gantries
- Packaging machine linear actuators
Installation notes:
Requires surface flatness ≤0.01mm/m and mounting surface roughness Ra1.6.
Use calibrated torque wrench (M6: 5.5-6.5N·m). Maintain 0.02-0.05mm clearance
between rail ends for thermal expansion. Apply lithium soap-based grease
(ISO VG32-68) during assembly.
