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 note:
Requires mounting surface flatness ≤0.01mm/m. Use torque-controlled screwdriver (0.7-0.9N·m for M4 screws).
Apply initial lubrication: 50% filling rate with ISO VG32-68 grease. Avoid mixing different preload classes in same system.

Precision linear motion system combining high rigidity and smooth movement. Features enhanced dustproof seals with triple-layer wipers (two metal scrapers + rubber seal). The BH suffix indicates drilled/tapped mounting holes at both rail ends for simplified installation. Designed for applications requiring precise repeat positioning within ±0.01mm accuracy.
Typical Applications:
- CNC router Z-axis guidance systems
- 3D printer gantry alignment
- Semiconductor wafer handling robots
- Medical imaging equipment sliding mechanisms
- Automated optical inspection (AOI) stages
Installation note:
Requires mounting surface flatness ≤0.01mm/m. Use torque-controlled screwdriver (0.7-0.9N·m for M4 screws).
Apply initial lubrication: 50% filling rate with ISO VG32-68 grease. Avoid mixing different preload classes in same system.
Maintenance Cycle:
- Relubrication: Every 6 months (normal use)
- Seal inspection: 12 months
- Recalibration: After 500km travel or impact events
