Airtac LSH Linear Guide Rail LSH25BK-F1N-N-B-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 contact angles (45°×45°) for balanced radial and reverse radial load capacity. The hardened steel raceway (HRC 58-62) ensures extended service life under heavy-duty cycling. Integrated oil retention grooves maintain lubrication efficiency, while the triple-seal design prevents particulate ingress in harsh environments.
- Precision CNC router Z-axis positioning systems
- Semiconductor wafer handling robots
- High-speed packaging machine pick-and-place units

Installation Protocol:
Clean rail mounting surface to ≤Ra1.6μm roughness. Use calibrated torque wrench (recommended 5.4N·m for M6 screws)
with alternating tightening sequence. Apply lithium soap-based grease (NLGI #2) through carriage lubrication ports
before initial operation. Avoid mixing carriages between rails due to selective assembly tolerances.
