Ultra-compact linear motion solution with optimized preload for smooth operation in confined spaces. Features hardened raceways (HRC58-62) and corrosion-resistant treatment, supporting high moment load applications. The staggered ball circuit design minimizes vibration transmission, making it ideal for precision positioning systems.
- Medical device XYZ-axis positioning
- Semiconductor wafer inspection equipment
- 3D printing extruder carriage systems
- Automated microscope stage movement
- Precision optical alignment mechanisms
Installation Note:
Requires surface flatness ≤0.02mm/m and mounting surface roughness Ra1.6μm.
Use torque-controlled tightening sequence (2.0-2.5N·m for M4 screws).
Avoid side-loading during assembly - use alignment jigs for parallel installation.
