About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX290-20S
The AirTAC SAIJ32X290-20-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The SUS420J2 stainless steel rod (code A) provides enhanced corrosion resistance compared to standard carbon steel.
This model includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors, which seat neatly into the sensor grooves on both sides of the extruded aluminum barrel. The rear adjuster acts purely as a mechanical stop to fine-tune the retract position without adding external stops, while the PT tapered port threads ensure a secure pneumatic connection.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 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 Adjustable Cylinder SAIJ32 SAIJ32AX290-20S Is Used
Product Changeover
Dial in the 270-290mm travel window during format changes on a packaging line, avoiding the need to physically swap out the entire cylinder for different package lengths.
End-Stop Calibration
Fine-tune the retract position to within a 20mm range during machine commissioning, ensuring precise mechanical alignment without bolting on external stopper blocks.
Variable Positioning
Handle varying product sizes on a single conveyor by adjusting the stroke end-point to push items accurately into staging areas.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX290-20S the Right Cylinder?
Choose this 32mm bore when an application requires precise end-position tuning on the fly, such as accommodating slight product size variations on a conveyor. If your setup needs greater thrust, stepping up to the 40mm bore increases push force to 628N at 0.5 MPa. Because the 290mm stroke is relatively long for a 32mm rod, external guiding is recommended to prevent excessive side-loading and premature seal wear.
The rear adjuster sets the travel end but does not lock the load without live air pressure; for true load-holding, consider the SAIL or BSAI series. This SAIJ variant supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. It is dimensionally interchangeable per ISO 15552, uses a PT G1/8 port, and operates at speeds of 30-800mm/s.

- ✓ 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 Adjustable Cylinder SAIJ32 SAIJ32AX290-20S FAQ
The maximum thrust is 82kgf at 1.0 MPa.
The rear mechanical adjuster allows you to shorten the effective stroke from the nominal 290mm down to 270mm, creating a 270-290mm usable travel window for fine-tuning the retract end position without replacing the cylinder.
