Airtac LSH Linear Guide Rail LSH25BK-HL-N-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.

High-rigidity linear guide with optimized load distribution, featuring corrosion-resistant treatment and enhanced dustproof capabilities through multi-layer sealing. The HL preload version balances smooth motion and vibration damping, ideal for applications requiring both precision and impact resistance. Requires periodic relubrication every 1,000km travel.
- CNC gantry mill Z-axis guidance systems
- Automated warehouse stacker cranes
- Lithium battery laser welding machines
- Semiconductor wafer handling robots
- High-speed packaging line linear actuators
Installation note:
Maintain parallelism within 0.05mm/m during mounting. Use M6 screws torqued to 8.8N·m ±10%
with Loctite 243. Avoid mixing carriages from different batches.
