Ultra-compact linear motion solution combining high rigidity with minimal space requirements. Features hardened steel rails with chrome plating (3-5μm thickness) and optimized ball circuit design for smooth operation under medium loads. The asymmetric ball groove configuration reduces vibration transmission by 30% compared to standard models.
- Precision laboratory automation stages
- Medical imaging equipment sliding mechanisms
- Semiconductor wafer handling robots
- 3D printer X/Y axis systems
- Optical inspection device positioning
- Desktop CNC machine slides
Installation guidelines:
Apply 25-30N·m torque for M4 mounting screws. Use 0.02mm feeler gauge to verify parallel alignment during installation. Avoid side-mounted configurations exceeding 15° from horizontal plane. For vertical use, limit dynamic loads to 60% of rated capacity.
