- Precision alignment in optical component assembly
- Valve actuation in compact fluid control systems
- Cartesian robot Z-axis positioning
- Medical device sterilization chamber door mechanisms
Installation guidelines:
Mount on flat surface with parallelism error <0.1mm/100mm.
For vertical mounting, use rod-end support bracket (ASNU12-20 recommended).
Maintain 0.3-0.6 MPa pressure for optimal cushioning performance.
