Ultra-slim linear motion solution combining high rigidity with minimal space requirements. Features staggered ball circuit design for smooth operation and reduced vibration. The BH suffix indicates special hardened steel balls (HRC62±2) for extended service life in high-cycle applications. Compatible with automatic lubrication systems through grease nipple (accessory).
- Medical device positioning stages
- Laboratory automation equipment (pipette arms, sample handlers)
- Desktop CNC and 3D printer Z-axis mechanisms
- Optical inspection system slides
- Semiconductor wafer handling robots
Installation note:
Requires mounting surface flatness ≤0.02mm/m. Use torque-controlled tightening (0.8-1.2Nm for M4 screws)
in cross pattern sequence. Avoid side load exceeding 10% of dynamic rating. Relubricate every 100km travel
or 6 months in clean environments.
