Ultra-compact linear motion solution featuring zero-backlash ball recirculation and dust-resistant triple sealing system. The hardened steel rail provides 58-62HRC surface hardness for extended service life. Optimized ball groove geometry ensures smooth motion (friction coefficient μ<0.003) while maintaining 20% higher rigidity than standard micro guides.
- Precision laboratory automation stages
- Semiconductor wafer handling robots
- Medical imaging equipment sliding mechanisms
- High-speed PCB drilling/spindles
- Optical lens positioning systems
- 3D printer X/Y-axis motion
Installation tip:
Achieve optimal performance by maintaining <0.02mm/m straightness during rail mounting.
Use 4.2N·m torque for M4 mounting screws with Loctite 243 threadlocker.
Thermal expansion compensation required for installations exceeding 500mm.
