Ultra-compact linear motion solution with optimized ball circuit design, delivering smooth movement and high rigidity in constrained spaces. Features hardened raceways and corrosion-resistant plating for extended service life. The integrated sealing system effectively blocks contaminants while maintaining low friction coefficients (μ<0.005). Requires periodic relubrication every 100km of travel.
- Precision medical imaging equipment stages
- Semiconductor wafer handling robots
- 3D printer X/Y axis mechanisms
- Optical inspection system positioning
- Laboratory automation sample handlers
- Desktop CNC milling machine slides
Installation note:
Ensure rail parallelism within 0.05mm/m using precision level during mounting.
Use torque-controlled wrench (recommended 1.2N·m for M3 mounting screws)
to prevent rail deformation. Avoid exposing to acidic vapors or conductive dust environments.
