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

Professional-grade linear motion solution featuring hardened raceways (HRC58-62) and oversized ball bearings for enhanced stiffness in multi-axis systems. The HL preload configuration balances smooth movement with vibration damping, making it ideal for CNC applications requiring both precision and impact resistance. Includes dual-side oil retention grooves and corrosion-resistant treatment.
- High-speed CNC gantry milling machines
- Automated optical inspection (AOI) equipment
- Semiconductor wafer handling robots
- Precision injection molding ejector systems
- Laser cutting machine Z-axis guidance
Installation protocol:
Mount on machined reference surface (Ra≤3.2μm). Use 4.9-6.9Nm torque for M6 bolts
with Loctite 243. Relubricate every 1,000km travel or 6 months. Avoid side-mounted
radial loads exceeding 15% of C0.
