Typical Applications:
- Precision positioning in automated assembly lines
- Clamping mechanisms with variable workpiece sizes
- Packaging machine ejector systems
- Die-casting machine core-pull operations
- Semiconductor handling equipment
Installation note:
For optimal performance, maintain 0.3-1.0mm clearance between cushion needle and end cover during adjustment.
Lubricate rod every 500km stroke travel in high-cycle applications.
Configuration Tips:
- Use with ARD20 series magnetic sensors for position feedback
- Pair with ASC200 series speed controllers for velocity-sensitive operations
- Install rod wipers (ASW80) in high particulate environments
