- Damping control for shock-sensitive pick-and-place robots
- Packaging machine stopper cylinder cushioning
- Medical device actuator speed regulation
- Automated door closure rate adjustment systems
Installation guidelines:
Install directly on cylinder exhaust ports for optimal speed control.
Perform initial adjustment at 0.5 MPa pressure.
Use Loctite 243 on threads if vibration exceeds 5G.
Recommended maintenance: Clean filter screen every 2,000 operating hours.
