Ultra-compact linear motion solution combining high rigidity with minimal space requirements. Features corrosion-resistant treatment and optimized ball circulation design achieving smooth movement (friction coefficient <0.005). The H-type carriage provides 30% higher moment resistance compared to standard models. Requires periodic relubrication every 1,000km travel distance.
- Medical device positioning stages
- Lab automation: PCR machines, sample handlers
- 3D printer X/Y axis systems
- Semiconductor wafer inspection equipment
- Robotic joint mechanisms (6-axis arms)
- Precision optical alignment systems
Installation tip:
Use 4.5Nm torque for M3 mounting screws. Maintain parallel alignment within
0.05mm/m during rail assembly. Apply LOCTITE 243 threadlocker for vibration resistance.
