Precision-adjustable industrial cylinder featuring dual cushion control with 15-stage damping adjustment. The 20S mounting flange allows secure 4-bolt fixation (M6x25 bolts recommended). Anti-rotation design maintains alignment during long-stroke operations. Built-in magnet slot for optional magnetic sensor installation (AISI 430F stainless steel piston).
- Press machine ejection systems requiring variable end-position damping
- Automated packaging line pusher mechanisms
- Glass cutting equipment with precise stroke control
- Plastic injection molding machine core pullers
- Automotive welding fixture positioning
Installation protocol:
Align cylinder axis within 0.2mm/m parallelism tolerance. For vertical mounting,
use rod-end support bracket (recommended for strokes >300mm). Adjust cushion screws
clockwise to increase damping force. Run 5-10 test cycles before full operation.
