About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX220-50S
The AirTAC SAIJ80X220-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 170 to 220 mm usable travel window.
This SKU is equipped with a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and includes a magnet for CMSE reed and DMSE solid-state sensors. The extruded aluminum barrel provides sensor grooves on both sides, and the PT tapered port thread ensures a tight pneumatic connection on the G3/8 air supply.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX220-50S Is Used
Product Changeover Dials
Quickly adjust the retract end-position by up to 50 mm when switching machinery between different product sizes, eliminating the need to physically swap cylinders.
Variable End-Stop Diverting
Fine-tune the stroke window from 170 to 220 mm on conveyor sorting gates to handle varying package dimensions on the fly without adding external hard stops.
Machine Setup Calibration
Dial in the exact end-of-stroke position during initial commissioning to perfectly time machine movements, compensating for mechanical tolerance stack-up.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX220-50S the Right Cylinder?
The 50 mm adjustment range is ideal for product changeovers on a production line, letting you set variable end-stops without swapping the cylinder or adding external mechanical stops. For holding a load without live air pressure, note that the rear adjuster acts only as a travel stop; you would need an external rod lock or a SAIL pneumatic lock cylinder instead.
Because the 220 mm stroke exceeds the 300 mm threshold where side-loading becomes a concern, ensure your setup includes an external guide rail to support the load. This cylinder uses a 25 mm rod and M20x1.5 rod thread, which provides high rigidity, but external guidance remains critical for long-travel stability. The mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 accessories, omitting the FB, CA, CB, and CR options.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ80 Adjustable Cylinder SAIJ80AX220-50S FAQ
The rear adjuster acts as an external stopper that lets you shorten the nominal 220 mm stroke by up to 50 mm, creating a usable travel window of 170 to 220 mm. It is a travel stop for end-position tuning, not a locking mechanism, and cannot hold a load without live air pressure.
