About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX290-20
The AirTAC SAIJ32X290-20 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 270-290 mm usable travel window, allowing you to dial back the nominal 290 mm stroke by up to 20 mm during commissioning.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads with a G1/8 connection. The extruded aluminum barrel includes sensor grooves on both sides. If positioning is required, adding a magnet enables the use of AirTAC CMSE reed and DMSE electronic sensors.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ32BX290-20 Is Used
Product Changeovers
Dial in the 270-290 mm travel window on the fly to accommodate slight variations in product dimensions without swapping the cylinder.
End-Position Tuning
Fine-tune the retract end-stop precisely during machine commissioning to avoid mechanical crashes and ensure perfect placement.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX290-20 the Right Cylinder?
The adjustable stroke is ideal for product changeovers or fine-tuning end positions without adding external stops. For fixed travel needs, a standard SAI cylinder is simpler. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Because the 290 mm stroke is relatively long for a 32 mm bore, an external guide is recommended to handle side loads. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an SAIL or BSAI cylinder. This model is dimensionally interchangeable per ISO 15552.
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 Adjustable Cylinder SAIJ32 SAIJ32BX290-20 FAQ
The rear adjuster screw lets you shorten the effective travel from the nominal 290 mm down to 270 mm. It functions as a mechanical stop to set the retract position and does not lock the load without continuous air pressure.
