About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX220-30
The AirTAC SAIJ80X220-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the effective travel between 190 and 220 mm without swapping out the unit.
This specific configuration features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance, alongside PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing for the direct mounting of AirTAC CMSE reed or DMSE electronic sensors if position feedback is later required.

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 SAIJ80AX220-30 Is Used
Product Changeover
Dial in the 190-220 mm travel window during format size changes on a packaging line, using the rear screw to set new end positions rapidly without changing hardware.
End-Stop Calibration
Achieve exact end-position tuning at machine commissioning, trimming up to 30 mm off the nominal stroke to perfect the seating of heavy 2513 N press assemblies.
Variable Positioning
Adapt actuator endpoints on the fly for automated material handling, using the external stopper to accommodate different pallet sizes while maintaining ISO 15552 mounting dimensions.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX220-30 the Right Cylinder?
Selecting this 80 mm bore over the smaller 63 mm variant steps the thrust up from 1559 N to 2513 N at 0.5 MPa, whereas moving to a 100 mm bore would yield 3927 N. The 30 mm rear adjustment screw is ideal for product changeovers on a line, letting you shift the end-stop precisely during commissioning rather than machining external stops. Keep in mind the rear adjuster functions strictly as a travel stop and does not hold the load mechanically; if static load-holding without live air pressure is required, an external rod lock or the AirTAC SAIL/BSAI series is necessary.
For a direct ISO 15552 replacement, match the 80 mm bore, 220 mm stroke, 30 mm adjustment range, PT port thread, and the SUS420J2 rod material. Because the 220 mm stroke is under the 300 mm threshold, side-load stress is moderate, but the 25 mm rod diameter still requires external guiding if subjected to significant lateral forces. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

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 SAIJ80AX220-30 FAQ
If pressure is increased to 0.7 MPa, the push force rises to 3518 N.
The rear adjuster acts as an external stopper that lets you mechanically shorten the stroke from the nominal 220 mm down to 190 mm. It sets the travel end and relies on the air cushion for deceleration, but it does not lock the load without continuous air pressure.
