- Optical inspection equipment stages
- Desktop CNC milling machine Z-axis
- Medical analyzer slide mechanisms
- High-speed pick-and-place actuators
Installation tip:
Use 0.02mm feeler gauge to verify parallel alignment during mounting.
Apply lithium soap-based grease (ISO VG32-68) through 4 maintenance ports
every 100km of travel. Avoid exposing to chemical vapors or abrasive particles.
