Airtac LSH Linear Guide Rail LSH25BK-HL-P-D-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 featuring optimized ball circuit design for smooth operation under heavy moment loads. The HL preload ensures minimal deflection in high-precision applications, while the triple sealing system effectively prevents particulate ingress. D-type end machining allows for simplified rail alignment during installation.
- CNC gantry machining centers (Z-axis applications)
- Semiconductor wafer handling robots
- High-speed packaging machinery (cartesian systems)
- Precision optical inspection equipment
- Medical imaging device sliding mechanisms
Installation note:
Requires 0.02mm/m alignment accuracy during mounting. Use torque-controlled wrench
(recommended 5.4N·m for M6 screws) and sequential tightening pattern. Thermal expansion
compensation required for installations over 1.5m length.
