A precision adjustable stroke cylinder featuring dual-position mechanical stoppers for mid-stroke positioning. The hexagonal adjustment nuts enable ±3mm micro-adjustment without disassembly. Its corrosion-resistant construction includes a double-sealed piston rod wiper for dusty environments.

Typical Applications:

• Variable clamping force fixtures in CNC machining centers
• Adjustable press mechanisms for electronic component assembly
• Position-variable material stops in conveyor systems
• Packaging machine flap adjustment units
• Semiconductor handling equipment with clearance control

Installation notes:

1. Use locknuts (not included) on adjustment screws after positioning
2. Maintain 0.3-1.0 MPa air pressure for optimal cushioning performance
3. Apply thread-locking compound to stopper screws in high-vibration environments
