Airtac LSH Linear Guide Rail LSH25HL3X1960S20AH-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 combining high rigidity and contamination resistance. Features optimized ball recirculation geometry for smooth operation under heavy cutting forces. The S20AH sealing system uses labyrinth structure with oil-impregnated felt for dustproof IP65 equivalent protection. Requires periodic lubrication every 100km travel.
- CNC gantry mill X-axis drives
- Automated pallet shuttle systems
- High-precision optical inspection equipment
- Die-casting machine ejection mechanisms
- Lithium battery stacking robots
Installation guidelines:
Ensure mounting surface flatness ≤0.05mm/m. Use 8.8 grade M6 bolts torqued to 8.5±0.5Nm in cross pattern.
Align rails within 0.1mm parallel tolerance over full length.
