Description
1. Self-aligning Capability: Features front-mounted X-type (45°×45°) arc raceway groove design with automatic alignment compensation. The internal mechanism absorbs minor mounting surface deviations to maintain high-precision, smooth, and stable linear motion.
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.
Category: Linear Guides | Brand: AIRTAC | Series: LSH
Installation protocol:
Requires torque-controlled tightening sequence (3.5-4.2Nm for M6 screws)
using cross pattern. Rail straightness should be verified with 0.02mm/m
tolerance using optical level before final locking.

High-rigidity linear motion system with optimized ball circuit design for vibration damping. Features staggered ball contact pattern (S20 marking) reducing noise by 15-20dB compared to standard models. Includes alignment marks for simplified multi-axis parallel installation.
Industrial Applications:
- CNC gantry mill Z-axis reinforcement
- Automated pallet shuttle systems
- High-precision optical inspection stages
- Lithium battery stacking machinery
- Semiconductor wafer handling robots
Installation protocol:
Requires torque-controlled tightening sequence (3.5-4.2Nm for M6 screws)
using cross pattern. Rail straightness should be verified with 0.02mm/m
tolerance using optical level before final locking.
Lubrication: Initial grease filling (ISO VG68) required.
Relubrication every 500km travel or 6 months in clean environments.
Compatible with most mineral-based greases (NLGI #2 recommended).
