Airtac LSH Linear Guide Rail LSH30BK-HL-P-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.

Industrial-grade linear motion solution with enhanced dust/contaminant resistance. Features optimized ball circuit design for smooth operation under combined loads (radial + moment). The HL preload ensures minimal deflection during high-speed reversals (up to 5m/s). Compatible with automatic lubrication systems through grease nipple ports.
- CNC gantry mill Z-axis drives
- Automated warehouse stacker cranes
- Semiconductor wafer handling robots
- High-speed packaging machinery
- Precision optical alignment stages
Installation protocol:
Clean rail with non-linting cloth and alcohol before assembly.
Use torque wrench (8-10Nm for M6 bolts) in cross-tightening sequence.
Avoid hammering during installation - impacts degrade ball track geometry.
