Ultra-compact linear guide system optimized for precision motion in constrained spaces. Features stainless steel rollers with chromium-plated rails for corrosion resistance in medical/lab environments. The dual-block configuration (N2) provides enhanced moment load capacity while maintaining ±0.01mm repeatability. Integrated sealing system prevents particulate ingress in cleanroom applications.
- DNA sequencing equipment Z-axis mechanisms
- Pharmaceutical tablet counting/packaging systems
- Semiconductor wafer inspection stages
- High-speed PCB component placement machines
- Endoscopic camera positioning arms
