Ultra-compact linear guide system optimized for space-constrained automation applications. Features hybrid construction with hardened steel rails and lightweight aluminum sliders, combining wear resistance with reduced moving mass. The AHT surface treatment provides enhanced corrosion protection (500hr salt spray test passed) and dry-running capability for intermittent use.
- Precision laboratory instruments (spectrometers, DNA sequencers)
- 3D printer X/Y axis motion systems
- Semiconductor wafer handling robots
- Medical imaging equipment sliding mechanisms
- Automated optical inspection (AOI) systems
Installation guidelines:
Ensure rail parallelism ≤0.05mm/m using precision level during mounting.
Apply initial lubrication to all ball tracks before first operation.
Use torque limiter (0.8-1.2Nm) for slider mounting screws to prevent over-constraint.
