About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX220-30S
The AirTAC SAIJ80X220-30-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. By turning the rear screw, you achieve a 190-220mm usable travel window, allowing precise end-position tuning during commissioning without swapping hardware.
This adjustable-stroke model includes a magnet for CMSE reed and DMSE electronic sensors, fitting neatly into standard sensor grooves on both sides of the extruded aluminum barrel. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear stopper sets the travel end and relies on the air cushion for deceleration, but it does not lock the load without live air pressure.

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 SAIJ80AX220-30S Is Used
Product Changeovers
Dial in the 190-220mm end-stop during rapid format changes on packaging lines without swapping cylinders or adding external mechanical stops.
Machine Setup
Fine-tune the retract position at commissioning to achieve exact tooling alignment, utilizing the 30mm adjustment range for perfect positioning.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX220-30S the Right Cylinder?
The 30mm adjustment window is ideal for product changeovers on a line, letting operators dial in the exact 190-220mm end-stop on the fly instead of machining external stops or reverting to a fixed-stroke SAI cylinder. To replace an ISO 15552 cylinder, match the 80mm bore, 220mm stroke, PT G3/8 port, and the -S magnet requirement.
Because the 220mm stroke is substantial, the 25mm rod and M20x1.5 thread handle high side loads, yet an external guide is still recommended for unsupported loads. For load-holding without continuous air pressure, integrate an external rod lock or look to the SAIL or BSAI series, as the SAIJ adjuster is strictly a travel stop, not a clamp or brake.
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 SAIJ80AX220-30S FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel by up to 30mm. This creates a 190-220mm usable stroke window for fine-tuning the end position without replacing the cylinder.
At 0.7MPa, the push force increases to 3518N.
