- Medical device positioning mechanisms (e.g., biopsy robots)
- Semiconductor wafer inspection equipment
- Compact CNC tool changers
- Laboratory automation slide rails
- Miniature Cartesian robots
Installation note:
Requires surface flatness ≤0.01mm/m and use of torque-limiting driver (0.6-0.8Nm for M3 screws).
Avoid cantilevered loads exceeding 15N·m. Perform running-in at 20% max speed for first 100 cycles.
