Precision-ground miniature guide system featuring dual carriages for enhanced load distribution. The hardened rail surface (HRC 58±2) ensures wear resistance, while the preloaded ball circuit design eliminates clearance vibration. Compatible with automatic lubrication systems through integrated grease nipples. Includes mounting datum surfaces for simplified alignment.
- High-speed PCB component insertion machines
- Medical diagnostic slide handlers
- Semiconductor wafer inspection stages
- Desktop CNC engraving axis systems
- Automated microscope focusing mechanisms
Installation protocol:
Apply 0.02-0.05mm preload using calibrated torque wrench (1.2-1.5N·m for M3 screws).
Maintain rail straightness within 0.1mm/m using precision level during mounting.
Run-in with ISO VG10 grease for 50 cycles at 0.5m/s before full operation.
