Ultra-compact linear guide system optimized for precision motion in constrained spaces. Features hardened raceways and precision-ground balls for smooth travel repeatability ±0.005mm. The PT suffix indicates medium preload (20μm preload) for reduced vibration in medium-duty applications. Compatible with stepper/servo motor systems.
- Medical device positioning stages
- Semiconductor wafer handling robots
- Desktop CNC milling machines
- 3D printer X/Y axis systems
- Automated microscope slide scanners
Installation note:
Use torque-controlled installation (M3 screws at 1.2N·m max) with reference surface flatness ≤0.02mm/m.
Avoid side-loading during assembly - align using master carriage technique.
