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
Mounting Protocol:
Use 18-22N·m torque for M6 mounting screws. Align rails with 0.02mm/m straightness tolerance using master-reference alignment. Compensate for thermal expansion by maintaining 20-25°C ambient temperature during installation.

High-rigidity linear motion system featuring optimized ball recirculation for smooth operation under heavy moment loads. The BK-series block incorporates an anti-creep design with 45° contact angles, delivering ±0.05mm/m positioning repeatability. Compatible with automatic lubrication systems through Zerk fittings (optional).
Industrial Applications:
- CNC router Z-axis drives requiring vibration damping
- Automated warehouse stacker cranes
- Glass cutting machine linear stages
- High-cycle packaging equipment with side-mounted actuators
- Semiconductor wafer handling robots
Mounting Protocol:
Use 18-22N·m torque for M6 mounting screws. Align rails with 0.02mm/m straightness tolerance using master-reference alignment. Compensate for thermal expansion by maintaining 20-25°C ambient temperature during installation.
Lubrication: Initial grease filling (ISO VG68) required. Relubricate every 500km travel or 6 months (whichever comes first). Increase relubrication frequency by 30% for vertical installations.
