- Plastic injection molding ejector systems
- CNC machine tool part positioning
- Automotive welding fixture actuation
- Packaging machine lid pressurization
Installation note:
Maintain 0.5mm minimum alignment tolerance during mounting. For vertical use exceeding 45° angle,
install an air dryer to prevent condensed water accumulation in lower cylinder chamber.
