High-precision adjustable stroke cylinder featuring manual stroke adjustment lock mechanism and dual-position sensing slots. The chrome-plated piston rod provides corrosion resistance in humid environments. Unique tapered cushion design reduces end-impact noise below 75dB. Requires 40μm filtered air and regular lubrication every 3,000km of cumulative travel.
- Variable height positioning in automated assembly lines
- Material handling equipment with adjustable clamping force
- Printing machinery for paper feed tension control
- Plastic injection mold core-pulling mechanisms
- Semiconductor wafer handling robots
Installation tip:
Maintain 0.5-1mm clearance between stopper plates during adjustment.
For vertical mounting, use rod-end support brackets (sold separately).
Cycle rate should not exceed 200mm/s for optimal seal life.
